How do alkanes, alkenes and alkynes differ from each other with respect to Reaction with bromine water

Explanation

### Step-by-Step Solution:

1. **Understanding Alkanes**:
- Alkanes are saturated hydrocarbons with single bonds between carbon atoms (C-C).
- They are generally inert and do not react with bromine water under normal conditions.
- However, in the presence of light or at high temperatures, alkanes can react with bromine to form alkyl halides. For example, when methane (CH₄) reacts with bromine (Br₂) in the presence of light, it produces bromomethane (CH₃Br) and hydrogen bromide (HBr).

2. **Understanding Alkenes**:
