The reaction of stilbene with pyridiunm hydrobromide perbrom

The reaction of stilbene with pyridiunm hydrobromide perbromide to make stilbene dibromide is a(n)? Select one a. overall oxidation of carbon b. overall reduction of carbon c. no net oxidation or reduction of carbon

Solution

Reaction of Stilbene with Pyridium hydrobromide perbromide (a.k.a pyridium tribromide) to make stibene dibromide is an electrophilic addition of Bromine to a double bond.

Here breaking of the double bond to add the Bromine takes place which indicates the reduction of double bond.

Option b is the right answer.
