Step by step solution

Proton transfer reaction

Proton transfer reactions are the reactions where the proton is taken out from a particular species and is acquired by another species. The conjugate base and the conjugate acid are obtained as the end product in a proton transfer reaction.

Classification of reaction a

The given reaction is a proton transfer reaction and the reaction of an electrophile and a nucleophile. In this particular reaction, HBr loses a proton leading to the creation of a conjugate base, ${Br}^{-}$ ion.

The molecule 2-propanol receives the proton from HBr leading to the generation of the conjugate base, and the reaction is given below:

Classification of reaction a

Classification of reaction b

The given reaction is a proton transfer reaction and the reaction of an electrophile and a nucleophile. The benzene molecule serves as the nucleophile, and it contributes its electron pair to the electrophile.

The electron pair is accepted by the electrophile, ${Br}^{+}$ ion, and the reaction can be given as follows:

Classification of reaction b
