When the alkene below is brominated with NBS reaction can occur at more than one carbon.

List all of the carbons in the structure below to which bromine can become attached upon reaction of the alkene with NBS.

NOTE: When the structure is symmetrical, you need to list every numbered carbon to which bromine may be attached even if it leads to same product as reaction at another carbon.

Respuesta :

Answer:

Four products are possible.(in attachment)

2,3,4,5 carbons attached to the bromine.

Explanation:

NBS is N-bromosuccinamide which is used to brominate the allylic and benzylic positions of the compound.

Mainly used for the allylic bromination Here, four products are possible among them two are formed by the direct allylic bromination and remaining two products are formed by the rearrangement of the radical formation.

2,3,4,5 carbons of the compound are attached to the bromine.
