Explanation

Let's break down each reaction step by step to determine the major product and its IUPAC name.

### (i) Reaction: `CH₃CH₂CH₂Cl + NaI (Heat) in Acetone`
1. **Identify the reaction type**: This is a Finkelstein reaction where iodine replaces chlorine.
2. **Reactants**: The reactant is 1-chloropropane (CH₃CH₂CH₂Cl).
3. **Product formation**: Chlorine (Cl) is replaced by iodine (I).
4. **Major product**: The product is 1-iodopropane (CH₃CH₂CH₂I).
5. **IUPAC name**: 1-Iodopropane.
