Q1. When comparing the physical states of the first two members of the aldehyde homologous series at room temperature, which observation is accurate?
Answer: Formaldehyde is a gas, acetaldehyde is a liquid
Explanation: Formaldehyde is a gas at room temperature, while acetaldehyde is a volatile liquid, reflecting the increase in boiling point with molecular size.
