Question

Which of the folllwing is more acidic (a) Ch3OH (b) C2H5OH (c) C3H7OH (d) H2O

Answer 1

$CH_{3} OH$ is most acidic among the following.

The acidic character of the alcohol is related to the durability of the alcohol-formed carbocation. The acidic character of the alcohols increases as the stability of carbocation decreases.

A tertiary carbocation is more stable than a secondary carbocation, which is more stable than a primary carbocation. The least stable is methyl carbocation.

(a) The methyl carbocation is formed by $CH_{3} OH$.

(b) The centre carbon is connected to another carbon atom, $C_{2}H_{5} OH$ is a primary alcohol. As a result, a main carbocation will form.

(c) The centre carbon is connected to three other carbon atoms, $C_{3}H_{7} OH$ is a tertiary alcohol. As a result, it will produce a secondary carbocation.

(d) It is the chemical formula of water. And water is neutral in nature. It is neither acidic nor basic.

The acidic character of the alcohol increases as carbocation stability decreases. Because methyl carbocation is the least stable. As a result,   will be the most acidic in nature.

Since (b), (c), and (d) are less acidic. Hence, option (a) is the correct answer.
