What is the type of hybridisation of each carbon in the following compounds ?
(i) `CH_3 CH_3`
(ii) `CH_3 CI`
(iii) `(CH_3)_2 CO`
(iv) `CH_3 CN`

Explanation

To determine the type of hybridization of each carbon in the given compounds, we will analyze each compound step by step.

### Step 1: Analyze the first compound `CH3CH3` (Ethane)
- Each carbon in ethane is bonded to three hydrogen atoms and one other carbon atom.
- Each carbon forms four sigma bonds (3 with H and 1 with another C).
- Since each carbon atom forms four sigma bonds, the hybridization is **sp³**.

### Step 2: Analyze the second compound `CH3Cl` (Methyl chloride)
