What is the state of hybridisation of the central carbon in a carbocation ?

Explanation

To determine the state of hybridization of the central carbon in a carbocation, we can follow these steps:

### Step 1: Identify the Structure of the Carbocation
Let's take the example of ethyl carbocation, which is represented as CH3-CH2^+. The central carbon in this case is the one that carries the positive charge.

### Step 2: Determine the Steric Number
The steric number is calculated using the formula:
\[ \text{Steric Number} = \text{Number of Bond Pairs} + \text{Number of Lone Pairs} \]
