Write the molecular formula of the third member of the homologous series of an organic compound with general formula `C_n H_(2n+1) OH`

Explanation

To find the molecular formula of the third member of the homologous series of organic compounds with the general formula \( C_nH_{2n+1}OH \), we can follow these steps:

### Step 1: Identify the general formula
The general formula given is \( C_nH_{2n+1}OH \). This indicates that we are dealing with alcohols, where \( n \) represents the number of carbon atoms in the molecule.

### Step 2: Determine the value of \( n \) for the third member
The first member of the series corresponds to \( n = 1 \):
- First member (n=1): \( C_1H_{2(1)+1}OH \) → \( C_1H_3OH \) → Methanol (CH₃OH)
