In the compound,

$\underset{(I)}{{CH}_{2}} = \underset{(II)}{CH} - C \underset{(III)}{\equiv CH}$

The most acidic hydrogen atom is

Options:

Answer:

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.
