Question

Among the following compounds, the strongest acid is (A) HC ≡ CH (B) C6 H6 (C) C2H6 (D) CH3OH

Tardigrade Admin · Accepted Answer

The correct order of acidic strength is

C H_{3} O H > C H \equiv C H > C_{6} H_{6} > C_{2} H_{6}

C H_{3} O H

is most acidic because

O

is more electronegative than

C

and it can accommodate negative charge as

C H_{3} O^{-}

. All the give compounds are neutral towards litmus.
