NEET2007ChemistryHydrocarbonsActual
Assertion : Acetylene on reacting with sodamide gives sodium acetylide and ammonia. Reason : (s p ) hybridised carbon atoms of acetylene are considerably electronegative.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion.
Step-by-step solution
( HC CH + NaNH ₂ Ether HC CNa ⁺+ NH ₃ ) ( C - H ) bond is strongly polar due to high electronegativity of carbon atom. Hence it gives ( H ⁺ )ion on reacting with a base or acetylene behaves as an acid.
