Question

Alcohols are isomeric with :

• A. acids
• B. ethers
• C. esters
• D. aldehydes

Answer 1

Answer: (B)

Two or more compounds having the same molecular formula but different physical or chemical properties are called isomers.

Functional isomers are compounds having same molecular formula or general formula but different functional group and different physical and chemical properties.
e.g., : Alcohols and ethers $\left(C_n{H}_{2n}+2O\right)$
Aldehydes and ketones $\left(C_n{H}_{2n}O\right)$
Acids and esters $\left(C_n{H}_{2n}{O}_2\right)$
