Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Given below are two statements:
Statement-1: Acetic acid exists as a dimer in benzene solution.
Statement-2: Intermolecular hydrogen bonding is stronger in non-polar solvents like benzene compared to polar solvents like water. Choose the correct option.
Options:
Answer:
Solution:
Statement-1 is correct. Acetic acid forms a cyclic dimer in non-polar solvents like benzene through two intermolecular hydrogen bonds. Statement-2 is also correct and explains Statement-1. In non-polar solvents, there is no competition from solvent molecules to form hydrogen bonds with acetic acid, allowing the acid molecules to associate strongly with each other. In polar solvents like water, water molecules compete to form hydrogen bonds with acetic acid, disrupting the dimer formation and leading to dissociation.
