Write product of the `CH_3 - CH_2 - CH = CH_2 + HCl`

Explanation

To solve the reaction of CH₃-CH₂-CH=CH₂ with HCl, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants are CH₃-CH₂-CH=CH₂ (butene) and HCl (hydrochloric acid).

2. **Understand the Reaction Mechanism**: The addition of HCl to an alkene occurs via an electrophilic addition mechanism. The double bond in the alkene acts as a nucleophile and attacks the electrophile (H⁺ from HCl).
