Q. The correct increasing order of acidity of the following alkynes
(1) $CH _3- C \equiv C - CH _3$
(2) $CH _3- C \equiv CH$
(3) $CH \equiv CH$

Hydrocarbons

Solution:

Only terminal alkynes show acidic nature. Ethyne is more acidic than propyne. But-$2$-yne is not acidic as it does not contain any hydrogen attached to $s p$ hybridised carbon.
