Q. 1. As the molecular weight of a carboxylic acid increases, solubility in water decreases. It is due to * a) hydrophobicity of the hydrocarbon portion overweighs the hydrophilicity of the carboxyl group. b) hydrophobicity of the carboxyl group overweighs the hydrophilicity of the hydrocarbon portion. c) ionisation of the carboxylic acid is increased. d) carboxylic acid exists as diverse.

Answer:
Solubility decreases as the carbon chain length increases because dipole forces become less important and dispersion forces become more predominant. ... Carboxylic acids of low molar mass are quite soluble in water. Table 15.4.
