Question

a. What products will be obtained from the addition of Br₂ to cyclohexene if H₂O is added to the reaction

mixture?

b. Propose a mechanism for the reaction.

Short answer

Double bond will attack on bromine atom and one bromine ion will release and another bromine ion will make bond with both carbon atoms which form double bond and with the addition of bromine it converts into single bond. Now oxygen lone pair of water molecule will attack on carbon which is bonded with bromine ion it can attack on either of the carbon and two substituents will form by releasing H⁺ ion.

Step-by-step solution

How reaction proceed

Double bond will attack on bromine atom and one bromine ion will release and another bromine ion will make bond with both carbon atoms which form double bond and with the addition of bromine it converts into single bond. Now oxygen lone pair of water molecule will attack on carbon which is bonded with bromine ion it can attack on either of the carbon and two substituents will form by releasing H⁺ ion.
