Question:
In the presence of peroxide, $HCl$ and $HI$ do not give anti-Markownikoff' s addition to alkenes because :
In the presence of peroxide, $HCl$ and $HI$ do not give anti-Markownikoff' s addition to alkenes because :
Updated On: Apr 1, 2026
- One of the steps is endothermic in HCl and HI
- Both HCl and HI are strong acids
- HCl is oxidizing and the HI is reducing
- All the steps are exothermic in HCl and HI
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Anti-Markownikoff addition is possible only in case of $HBr$ and not in $HCl$ and $HI$. In $HBr$ both the chain initiation and propagation steps are exothermic, while in $HCl$, first step is exothermic, and second step is endothermic and in $HI$, no step is exothermic. Hence $HCl$ and $HI$ do not undergo anti-Markownikoff?s addition.

Hydrocarbons
Hydrocarbons can be described as organic compounds that consists only hydrogen and carbon atoms. These compounds are of different types and thereby have distinct natures. Hydrocarbons are colorless gases and are known for discharging faint odours. These have been categorized under four major classes named as alkynes, alkanes, alkenes, and aromatic hydrocarbons.
Types of Hydrocarbons
- Saturated hydrocarbons - Saturated hydrocarbons are those compounds where there is a single bond exists between carbon atoms and are saturated with atoms of hydrogen.
- Unsaturated hydrocarbons - Hydrocarbons comprises of at least one double or triple bond between carbon atoms are known as unsaturated hydrocarbons.
- Aliphatic hydrocarbons - The term denotes the hydrocarbons formed as an outcome of the chemical degradation of fats. Aliphatic hydrocarbons are basically chemical compounds.
- Aromatic hydrocarbons - They are distinguished because of the presence of benzene rings in them. They give away distinct types of aroma. These hydrocarbons comprises of only hydrogen and carbon atoms.
