That's not quite correct and can be quite easily to be shown as wrong by looking up data tables and/or MSDS. Sugars, such as glucose, have many hydroxyl (OH) groups, which tend to increase the solubility of the molecule. Which of the following molecules would you expect to be more soluble in water? Explain why. Alcohol can be dumped into the ocean, and then alcohol would be in water, but generally, there is no Best Answer: The hydroxyl group (OH) is polar. MULTIPLE CHOICE. NOTE: Possibly confusing is a molecule like O_2, which has no bonds between O and H, but rather just a double bond between the two atoms of oxygen. Water is polar. Solute-solvent interactions, which involve hydrogen bonding, are relatively strong b. For this sole reason we would predict that it should give greater aqueous solubility. Methanol makes strong covalent bonds to water when it dissolves. Since water is a polar solvent, I would expect the second molecule to be more soluble in water because it has more polar groups. CH2Cl2 is a polar substance since the C-Cl bonds has a higher dipole moment than the C-H bonds. These interactions are called intermolecular forces (IMFs), and physical properties of compounds can be inferred by the type of IMFs. CHM 152 Key Chapter 13 practice questions 1. c. Alcohols, in comparison, are readily soluble in water. Consider a gas mixture of N2 and CO2, in which case is the CO2 most soluble? 1.

This was some of the first evidence that cells were surrounded by a lipid membrane. CH3CO2H 4. Using the axiom, “like dissolves like”, hexane would water-insoluble. Choose the one alternative that best completes the statement or answers the question. 1-propanol has 1 polar end. For each compound, would you expect greater solublity in hexane or in water? Explain. Now the alkane is nonpolar molecule and hence its interaction is weak with water. The first molecule has one polar end and one non-polar end. As a physical scientist, you should look up the literature to see if this prediction is true. Which molecule will you expect to be more soluble in water, CH3CH2CH2OH Best Answer: Water is a polar substance, therefore the more polar molecule will dissolve in it. . Therefore, CH2Cl2 will be more soluble in water. 1. All three of these molecules have the ability to hydrogen bond with water because of their OH groups. ICl d. Butanoic acid has the shortest pendant alkyl chain. Since polar compounds dissolve in polar solvents, the order of solubility in the polar solvents is: Propanol > Ethyl methyl ether > Propane. propanoic acid is more soluble in water than 1-butanol.

CH3OH, CH3CO2H and CH3NH2 are polar and can participate in hydrogen-bonding interactions with water, which would make these compounds quite water-soluble. 1 g of \(\ce{LiCl}\) dissolve in 100 mL of acetone. If the bonds in the network are stronger, then the salt will not be soluble in water. Because the dipole moment of acetone (2. For amlecultpossess a dipole moment, the following condition is necessary but not sufficient. e. . 59) The reagent which converts a carbonyl group of a ketone into a methylene group is: A) NaBH4, CH3CH2OH B) LiAlH[OC(CH3)3]3 This means that carbon dioxide is less soluble in water than polar molecules are. Boiling point: Water has a higher boiling point than predicted on the basis of its molar mass. This is a prediction. CH 3 OCH 3 or CH 3 CH 2 OH 53) Answer: CH 3 CH 2 OH is more soluble in water since it can donate a hydrogen bond to water and accept a hydrogen bond from water. 31. The solubility of carbon dioxide is increased when the water is cold, and decreased greatly when the water is warm. CH3CH2NH2 on the other hand has a polar C-N bond, but it also can form hydrogen bonds. Solubility in water depends on hydrogen bonding.

From what I learned, counting the carbons can help determine it, but what if they have the same amount of carbons? Do I start look at the oxygens and hydroxyl groups? Write a one sentence answer Explain in detail All the molecules contain a polar group. The solubility of organic molecules is often summarized by the phrase, "like dissolves like. where 1. the more polar the solute, the better it dissolves in water. CH3OCH3 can only accept a hydrogen bond from water; it does not have hydrogen which can hydrogen bond to water. Predict which solvent will dissolve more of the given solute: a) Sodium Chloride in methanol (CH3OH) or in 1-propanol (CH3Ch2Ch2OH) Ans. Alkanes are not capable of hydrogen bonding with water. So it is soluble in polar solvents like water and methanol. Background Compounds interact with each other differently depending on their polarity. Ans: Topic: Isomers, Functional Groups. The polar covalently bonded water molecules act to exclude nonpolar molecules, causing the fats to clump together. Why? Ans: Sodium chloride, which is an ionic substance, is soluble in a polar solvent such as water, but not in a non-polar solvent such as hexane. Based on your knowledge of intermolecular forces, which of these would you expect to have the highest boiling point: a) propanone, or b) 1-propanol IB Chemistry - Revision Show the mechanism of the reaction between C3H6 + HBr.

There is no alcohol present in any water unless it is labeled that there is alcohol in water. 8 g/L. CH3OH 3. If the attraction to the water molecule is greater than the attraction to the other atoms in the network, the water will pull atoms away from the network and the salt will dissolve. In case of alcohols for example, first three alcohols are highly soluble, the correct term is miscible, as they are both liquids. Number one is the most soluble because it has the shortest hydrocarbon chain and because it has two OH groups. This aspect of water is illustrated in Figure 4. Hope this helps. A similar principle is the basis for the action of soaps and detergents. nonpolar. Best Answer: Water is a polar substance, therefore the more polar molecule will dissolve in it. You know that water is polar because of it's structure. To unlock this lesson you Vitamin Solubility Molecular Basis for Water Solubility and Fat Solubility. c) Lard is non polar. b. HOCH2CH2CH2OH is more soluble in water becase water is polar, therefore you look for the one that is the most polar covalent bond, which means that both ends of HOCH2CH2CH2OH is polar compared to the other one CH3CH2CH2OH. 77. (a) CH3CH2OCH2CH3 or CH3CH2CH2CH2CH3 (b) CH3CH2OCH2CH3 or CH3CH2CH2OH (c) CH3CH2NHCH3 However, they can have a partial charge and be slightly soluble in water if the group attached to benzene is a lot more or less electronegative than the benzene ring. 9 g/L whereas maleic acid (the cis-isomer) has a solubility of 478.

Which molecule All three of these molecules have the ability to hydrogen bond with water Number one is the most soluble because it has the shortest hydrocarbon Longer carbon chains make a molecule less soluble because they are non-polar. Overton discovered that substances that dissolve in lipids pass more easily into the cell than those that dissolve in water. Alkanes and ethers are non-polar and practically insoluble in water (a polar solvent). Aqueous solutions of iodine are prepared using potassium iodide solution which dissolves iodine as a complex anion. Comments to the instructor: Hexane, CH3CH2CH2CH2CH2CH3, is a hydrocarbon, and nonpolar. Draw a 3-dimensional structure of a water molecule, including any lone pairs of electrons, and indicate the dipole moment. For example, liquid water forms on the outside of a cold glass as the water vapor in the air is cooled by the cold glass, as seen in Figure 2. CH3NH2 Correct Answer: 1. Maleic anhydride would also react in water to form maleic acid. propanoic and HOCH2CH2CH2OH. Two hydrogens are bonded the an oxygen. 40. asked by Ashley on May 26, 2009; Chemistry permeability of molecules Introduction: In the late 1800's, E. Intermolecular Forces Explaining macroscopic behavior: viscosity • Viscosity is the resistance to flow in liquids • Viscosity is dependent on more than just molecule size – it also depends on the kinds of attractive forces between molecules • Viscosities of various liquids at 20ºC (in centipoise) Liquid Viscosity (cp) Type of IM attraction Nevertheless, the ether oxygen can act as a hydrogen bond acceptor in combination with better hydrogen bond donors like OH groups, which explains why diethyl ether is sparingly soluble in water despite its low polarity (69 g/l at 20 °C ). 53) Which compound is more soluble in water?
