Name the type of hybridisation of each C-atom in a molecule of (i) propylene (propene) (ii) propyne.
How many ` sigma and pi`-bonds are present in each case ?

Explanation

To solve the question, we will analyze the hybridization of each carbon atom in propylene (propene) and propyne, and then count the number of sigma and pi bonds present in each molecule.

### Step-by-Step Solution:

**(i) Propylene (Propene)**

1. **Identify the structure of propylene**:
Propylene (C3H6) has the structure CH3-CH=CH2.
