In the compound,&

$\mathop{CH₂}_{( I )} = \mathop{CH}_{( II )} - C\mathop{≡ CH}_{( III )}$

The most acidic hydrogen atom is

Options

AOnly $I$
BOnly $II$
COnly $III$
DAll are equally acidic

Correct answer

C. Only $III$

Step-by-step solution

The hydrogen attached with most electronegative carbon will be the most acidic.

The hydrogen, attached with $sp$ -hybrid $C$ -atom is most acidic because of highest electronegativity of $sp$ hybrid carbon atom, $H$ atom becomes relatively more acidic.
