Detailed Solution

Concept- A homologous series is a series of compounds with similar chemical properties and some functional groups different from the subsequent

{CH}_{2}

member.
For example-Alkanes of the general formula

C_{n} H_{2 n + 2}

, alkenes of the general formula

C_{n} H_{2 n}

and alkynes of the general formula

C_{n} H_{2 n - 2}

form the most basic homologous series in organic chemistry.
Now, alcohol series is also one of the homologous series and its general formula is

C_{n} H_{2 n + 2} O

Therefore, the first member of the alcohol series is

C H_{4} O

. It can also be written as

C H_{3} OH

.
To determine the fourth member of this series, we can simply put n = 4 in the general formula. Thus, the chemical formula of fourth member of the alcohol series is-

C_{4} H_{10} O

C H_{3} {CH}_{2} {CH}_{2} {CH}_{2} OH

.
Hence, the correct option is (3).
