Question

Molecular formula of the functional isomer of methyl formate is ____________.

विकल्प

• C₂H₄O₂

• C₃H₆O₂

• C₄H₈O₂

• C₅H₁₀O₂

Answer 1

Molecular formula of the functional isomer of methyl formate is C₂H₄O₂.

Explanation:

Aliphatic esters and aliphatic monocarboxylic acids are functional isomers. Therefore, the functional isomer of methyl formate (HCOOCH₃) is acetic acid (CH₃COOH). By definition of isomers, both methyl formate and acetic acid have the same molecular formula viz., C₂H₄O₂.
