Find the total isomer obtained by trichlorination of propane.

Explanation

To find the total isomers obtained by the trichlorination of propane, we will follow these steps:

### Step 1: Understand the Structure of Propane
Propane (C3H8) has a straight-chain structure with three carbon atoms. The structural formula can be represented as CH3-CH2-CH3.

### Step 2: Identify the Chlorination Process
Trichlorination involves replacing three hydrogen atoms in propane with chlorine atoms. This can occur at different positions on the carbon chain, leading to various structural isomers.
