a) Interpretation: The product(s) formed when the alkene shown reacts with NBS is/are to be given. Concept introduction: NBS is used mainly for allylic bromination. An unsymmetrical alkene will lead to a mixture of products as different allyl radicals will be produced as a result of delocalization. The products are not formed in equal amounts because the intermediate allylic radicals are not symmetrical and the reaction at two ends will not take place to the same extent. Reaction at less hindered primary side is more favored. To give: The product(s) formed when the alkene shown is treated with NBS.

Answer 1

Question

Chapter 10.SE, Problem 15VC

Interpretation Introduction

a)

Interpretation:

The product(s) formed when the alkene shown reacts with NBS is/are to be given.

Concept introduction:

NBS is used mainly for allylic bromination. An unsymmetrical alkene will lead to a mixture of products as different allyl radicals will be produced as a result of delocalization. The products are not formed in equal amounts because the intermediate allylic radicals are not symmetrical and the reaction at two ends will not take place to the same extent. Reaction at less hindered primary side is more favored.

To give:

The product(s) formed when the alkene shown is treated with NBS.
