A compound is treated with N a N H 2 to give sodium salt. Identify the compound
Options
- AC 2 H 2
- BC 6 H 6
- CC 2 H 6
- DC 2 H 4
Correct answer
A. C 2 H 2
Step-by-step solution
Only C 2 H 2 (acetylene) has acidic H-atoms and hence reacts with N a N H 2 to form sodium salt, i.e., HC ≡ CH + NaNH 2   → HC ≡ C Θ Na ⊕ + NH 3
