Question

What is the major product of each of the following reactions? Assume that there is an equivalent amount of each reagent.

Short answer

a)

b)

Step-by-step solution

How will reaction proceed

a) Markoniv addition takes place. HBr dissociates into H⁺ and Br^-, and negative ion will go towards that double bonded carbon which has less number of H atoms, and positive ion will go towards that double bonded carbon which has more number of H atoms.

b) Markoniv addition takes place. HBr dissociates into H⁺ and Br^-, and negative ion will go towards that double bonded carbon which has less number of H atoms, and positive ion will go towards that double bonded carbon which has more number of H atoms.

Final answer

The major products are-

a)

b)
