  3. C.(C)
  4. D.(D) red phosphorus

Correct Answer

(A) (A)

Solution & Explanation

\textbf{Answer:} (A) . \textbf{Solution:} Heating the sodium salt of a carboxylic acid with soda-lime (a mixture of and ) brings about decarboxylation, replacing the group with . Sodium propanoate thus loses (captured as ) to give ethane. The missing component of soda-lime is .
