Propene to 1-Iodopropane
To convert propene to 1-iodopropane, you can use hydroiodic acid (HI). The alkene undergoes electrophilic addition with HI, where the iodine atom adds to the carbon of the double bond with the most hydrogen atoms (Markovnikov's rule). \[ \text{CH}_2\text{CH} \text{CH}_3 + \text{HI} \rightarrow \text{CH}_3\text{CH}_2\text{I} \]
