The general formula of a homologous series of carbon compounds is `C_n H_(2n+1) OH` . Write the molecular formula of the fourth and the fifth members of the series.

Explanation

To find the molecular formulas of the fourth and fifth members of the homologous series represented by the general formula \( C_n H_{2n+1} OH \), we will follow these steps:

### Step 1: Identify the value of \( n \) for the fourth member.
For the fourth member of the series, we set \( n = 4 \).

### Step 2: Substitute \( n \) into the general formula.
Using the general formula \( C_n H_{2n+1} OH \):
- Carbon (C) part: \( C_n = C_4 \)
