Identify primary, secondary, tertiary and quaternary carbon atoms in the following compound :
` CH_3 - underset(CH_3) underset(|) overset(CH_3) overset(|) C-overset(C_2 H_5 ) overset(|) CH - CH_3`

Explanation

To identify the primary, secondary, tertiary, and quaternary carbon atoms in the given compound, we will first define what each type of carbon atom is:

1. **Primary Carbon (1°)**: A carbon atom that is bonded to only one other carbon atom.
2. **Secondary Carbon (2°)**: A carbon atom that is bonded to two other carbon atoms.
3. **Tertiary Carbon (3°)**: A carbon atom that is bonded to three other carbon atoms.
4. **Quaternary Carbon (4°)**: A carbon atom that is bonded to four other carbon atoms.

Now, let's analyze the given compound step by step:
