What are the hybrid states of C atoms in alkanes, alkenes and alkynes?

Explanation

To determine the hybrid states of carbon atoms in alkanes, alkenes, and alkynes, we can follow these steps:

### Step 1: Understand Hybridization
Hybridization involves the mixing of atomic orbitals to form new hybrid orbitals. The type of hybridization depends on the steric number, which is calculated based on the number of sigma bonds and lone pairs around a carbon atom.

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