How many `sigma ` and `pi` bonds are present in `CH_3-CH=CH_2`?

Explanation

To determine the number of sigma (σ) and pi (π) bonds in the compound `CH₃-CH=CH₂`, we can follow these steps:

### Step 1: Draw the Structure
The structure of `CH₃-CH=CH₂` can be drawn as follows:
- The first carbon (C1) is bonded to three hydrogen atoms (H).
- The second carbon (C2) is bonded to one hydrogen atom (H) and has a double bond with the third carbon (C3).
- The third carbon (C3) is bonded to two hydrogen atoms (H).
