Indicate the primary , secondary , tertiary and quanternary carbon atoms in the following : (i)3-Ethyl-2-methylhexane , (ii)2,2,4-Trimethylpentane .

Explanation

To determine the primary, secondary, tertiary, and quaternary carbon atoms in the compounds 3-Ethyl-2-methylhexane and 2,2,4-Trimethylpentane, we will follow these steps:

### Step 1: Draw the Structures
1. **3-Ethyl-2-methylhexane**:
- Hexane has 6 carbon atoms in a straight chain.
- At the 2nd carbon, add a methyl group (CH₃).
- At the 3rd carbon, add an ethyl group (C₂H₅).
