Identify the compound (B) in given reaction.
\(\mathrm{CH}_3 \mathrm{Cl} \xrightarrow{\mathrm{KCN}}(A) \xrightarrow{\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}}(B)\)
- A \(\mathrm{CH}_3 \mathrm{NH}_2\)
- B \(\mathrm{HCOOH}\)
- C \(\mathrm{CH}_3 \mathrm{COOH}\)
- D \(\mathrm{CH}_3 \mathrm{COCH}_3\)
Answer & Solution
Correct Answer
(C) \(\mathrm{CH}_3 \mathrm{COOH}\)
Step-by-step Solution
Detailed explanation
When chloromethane reacts with potassium cyanide, it will produce methyl cyanide (A) and potassium chloride. It is a nucleophilic substitution reaction in which cyanide ion will displace chloride ion. On further step, methyl cyanide gets hydrolysed and give acetic acid (B).
