Question

Aldehydes have much lower boiling points than alcohols with a similar molecular weight.

a. True
b. False

Answer 1

Aldehydes have lower boiling points than alcohols with a similar molecular weight due to their molecular structure and intermolecular forces. Aldehydes have a polar carbonyl group (C=O) that can form dipole-dipole interactions. However, they do not have hydrogen bonding with each other, unlike alcohols.

Step-by-step explanation:

Aldehydes have lower boiling points than alcohols with a similar molecular weight due to their molecular structure and intermolecular forces.

Aldehydes have a polar carbonyl group (C=O) that can form dipole-dipole interactions. However, they do not have hydrogen bonding with each other, unlike alcohols.

Alcohols, on the other hand, have an -OH group that allows for hydrogen bonding, resulting in higher boiling points compared to aldehydes.
