1

B

2

C

Explanation:

Stability of carbocation $\propto$ number of $α - H$

$\overset{+}{{CH}_{3}}$ has not any $α$ -hydrogen due to which it is unstable.

III

>

I

>

I

>

III

4 I

>

III

>

II

Explanation:

The electron withdrawing group decreases the electron density at acetylenic carbon due to which bond polarity increases between $C - H$ thus acidity increases. (II) compound is more acidic than I because (II) has the more acidic hydrogen. Thus, the order of acidic nature will be-
$II > I > III$
