Peroxide effect is observed for which of the following when added to propane с C (A) HCI (B) HBO (C) HI (D) A1]​

Answer 1

Answer:

option a is the correct answer

Answer 2

Peroxide effect when added to propene

Explanation:

• Peroxide-effect is observed in only case when hydrogen bromide react. All other hydrogen halide do not possess this effect

• The peroxide effect also known as kharasch effect

• In peroxide-effect the reactant undergo according to anti-markovnikov rule

• HI and HCl do not possess this effect due to addition of this to propene result in endothermic reaction. Therefore the reaction become unfavourable.

• Addition of $HBr$ to propene to form 2 Bromo propene
• In the absence of peroxide all hydrogen halide react according to  markovnikov rule
