Question

why boiling point of p-hydroxybenzaldehyde is higher than salicylaldehyde

Answer 1

Answer:

To break these intermolecular H-bonds, a large amount of energy is needed. Consequently, p- hydroxybenzaldehyde has a much higher m.p. & b.p. than that of o- hydroxybenzaldehyde. As a result, o- hydroxybenzaldehyde is a liquid at room temperature while p- hydroxybenzaldehyde is a high melting solid.
