Question

o-Hydroxybenzaldehyde is a liquid at room temperature while p-hydroxybenzaldehyde is a high melting solid because of (A) H-bonding (B) ionisation energy (C) electron gain enthalpy (D) lattice enthalpy

Tardigrade Admin · Accepted Answer

o-Hydroxybenzaldehyde shows intramolecular hydrogen bonding whereas p-hydroxybenzaldehyde has intermolecular hydrogen bonding. Thus p-hydroxybenzaldehyde is an aggregate of a number of molecules and therefore, it is a high melting solid.
