Question

Write the product/s formed in the following reactions a) Addition of bromine to but-2-ene b)Addition of HBr to pent -2-ene c)Addition of  HBr to pent-1-ene in the presence and absence of peroxide​

Answer 1

ANSWER: FOLLOWING

Explanation:

1)As but-2-ene bubbles through the bromine solution and reacts with the bromine, the bromine adds across the double bond and so the solution changes from brown to colourless.

2)The addition of HBr to Pent-2-yne gives a bromo compound having molecular formula C5H9Br

3)When Pent-1-ene Reacts with HBr in Presence of H2O2, 1-Bromopentane will be formed.
