Carboxylic acids have higher boiling points than their corresponding alcohols primarily because:
  • a)
    molecular weight is increased by the additional carboxyl group.
  • b)
    the pH of the compound is lower.
  • c)
    acid salts are soluble in water.
  • d)
    hydrogen bonding is much stronger than in alcohols.
Correct answer is option 'D'. Can you explain this answer?

The boiling points of compounds depend on the strength of the attractive forces between molecules. In both alcohols and carboxylic acids, the major form of intermolecular attraction is hydrogen bonding; however, hydrogen bonding is much stronger in carboxylic acids as compared to alcohols because carboxylic acids are more polar and the carbonyl also contributes to hydrogen bonding in addition to the hydroxyl group. The stronger hydrogen bonds elevate the boiling points of carboxylic acids compared to alcohols. Boiling points also depend on molecular weight, choice (A), but in this case, the difference in molecular weight is insignificant compared to the effect of hydrogen bonding. Choices (B) and (C) are both true but do not explain the difference in boiling points.

Q.What is the primary factor that determines whether molecules can passively diffuse through the cell membrane?Cell membranes are composed of phospholipids and serve as the boundary for cells. Phospholipids consist of a pair of fatty acids, which can have carbon-carbon double bonds or not, connected to a three-carbon glycerol with a phosphate group. The structure of phospholipids forms a bilayer with hydrophilic phosphate ends facing the outer and inner surfaces of the membrane, while the hydrophobic fatty acid chains extend into the space between these surfaces. This selectively permeable membrane facilitates the exchange of substances between the cells interior and its environment.Due to the hydrophilic and hydrophobic nature of the plasma cell membrane, only certain molecules can passively diffuse between the cells interior and the environment. The fluidity of the membrane affects passive transport, and the presence of other molecules, such as cholesterol, can significantly impact its fluidity. Temperature also influences membrane fluidity. Researchers conducted measurements to compare the speed of oxygen molecules (O2) moving through three types of membranes (lens lipid, POPC/CHOL, and POPC) with their movement through water. These measurements were conducted at different temperatures.
