In the compound, CH_2(I)=CH(II)-C≡CH(III) The most acidic hydrogen atom is

Q6 / 125 · BITSAT 2017 · Chemistry

In the compound,
$\underset{(I)}{{CH}_{2}} = \underset{(II)}{CH} - C \underset{(III)}{\equiv CH}$
The most acidic hydrogen atom is

A
Only $I$
B
Only $II$
Correct answer
C
Only $III$
D
All are equally acidic

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.

Hence, the correct answer is option: 'C'.
