Assertion: Ethyne reacts with sodium met...

Assertion: Ethyne reacts with sodium metal and sodamide to form sodium acetylide with the liberation of dihydrogen gas.
Reason: Alkynes are highly unsaturated.

A

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

B

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

C

If assertion is true but reason is false.

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
