Question

The step-down decarboxylation of sodium propanoate ($CH_3CH_2COONa$) using soda-lime produces which hydrocarbon?

Answer: B

💡 Solution & Explanation

Decarboxylation with soda-lime ($NaOH + CaO$) removes the entire $-COONa$ group as $Na_2CO_3$, yielding an alkane with one less carbon than the parent carboxylate. Sodium propanoate yields ethane.
