Addition of HI to double bond of propene yields isopropyl iodide and ...
Explanation:
When propene reacts with HI, the addition of HI to the double bond can occur in two ways: Markovnikov addition and anti-Markovnikov addition. In the case of propene, the major product formed is isopropyl iodide (2-iodopropane) rather than n-propyl iodide (1-iodopropane). This is because the addition proceeds through a more stable carbonium ion.
Markovnikov Addition:
- In Markovnikov addition, the hydrogen atom of HI adds to the carbon atom with fewer hydrogen atoms attached (the less substituted carbon atom) in the double bond.
- As a result, the iodine atom adds to the carbon atom with more hydrogen atoms attached (the more substituted carbon atom) in the double bond.
- This leads to the formation of the more stable carbonium ion intermediate.
Reason for the Major Product:
- In the case of propene, when it reacts with HI, the less substituted carbon atom in the double bond undergoes addition with the hydrogen atom of HI.
- This forms a more stable secondary carbonium ion intermediate.
- The more substituted carbon atom, which would have formed the n-propyl iodide product, forms a less stable primary carbonium ion intermediate.
- The more stable secondary carbonium ion intermediate is formed due to the greater stability of the secondary carbocation compared to the primary carbocation.
- Therefore, the major product formed is isopropyl iodide (2-iodopropane) rather than n-propyl iodide (1-iodopropane).
Summary:
- The addition of HI to propene proceeds through a more stable carbonium ion intermediate.
- The less substituted carbon atom in the double bond undergoes addition with the hydrogen atom of HI, forming a more stable secondary carbonium ion intermediate.
- This leads to the formation of isopropyl iodide (2-iodopropane) as the major product.
