What is the type of hybridisation of each carbon in the following compounds?
(a) `CH_(3)-CH_(3)`
(ii) `(CH_(3))_(2)CO`

Explanation

To determine the type of hybridization of each carbon in the given compounds, we will analyze the molecular structures of the compounds and count the number of sigma bonds and lone pairs around each carbon atom.

### Step-by-Step Solution:

**(a) For `CH3-CH3`:**
1. **Draw the Structure:**
- The structure of ethane (`CH3-CH3`) consists of two carbon atoms connected by a single bond, with three hydrogen atoms attached to each carbon.
