HC ≡ CH + NaNH2 xrightarrow textEther HC ≡ C- Na+ + NH3 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.

Reason: sp hybridised carbon atoms of acetylene are considerably electronegative.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

$H C \equiv C H + N a N H_{2} Ether H C \equiv C - N a + + N H_{3}$

$C - H$ 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.
