How is 1-iodobutane obtained from 1-butene?

Explanation

To obtain 1-iodobutane from 1-butene, we can follow a series of chemical reactions. Here’s a step-by-step solution:

### Step 1: Hydrohalogenation of 1-butene
1. Start with 1-butene (CH3-CH2-CH=CH2).
2. React 1-butene with hydrogen bromide (HBr) in the presence of peroxides. The presence of peroxides leads to an anti-Markovnikov addition.
3. The product of this reaction is 1-bromobutane (CH3-CH2-CH2-CH2Br).

**Hint:** The addition of HBr to alkenes can follow Markovnikov or anti-Markovnikov rules depending on the conditions used.
