Arrange the following in decreasing acidic strength.
1 A $>$ B $>$ C $>$ D
2 B $>$ A $>$ C $>$ D
3 D $>$ C $>$ A $>$ B
4 D $>$ C $>$ B $>$ A
Explanation:
Acidic character depend on the –I effect and –R effect, lesser the –ve charge on the OH group more is the acidic strength.

Which of the following lacks hyperconjugative stability?
1 $\mathrm{B}$
2 $\mathrm{A}$
3 $\mathrm{D}$
4 $\mathrm{C}$
Explanation:
Stability of carbocation $\propto$ number of $\alpha-\mathrm{H}$ $\stackrel{+}{\mathrm{CH}_{3}}$ has not any $\alpha$-hydrogen due to which it is unstable.

The decreasing order of acidic nature of the following compounds
1 III $>$ II $>$ I
2 II $>$ III $>$ I
3 II $>$ 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 $\mathrm{C}-\mathrm{H}$ 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- $\text { II }>\text { I }>\text { III }$
