Answer 1

The reaction is shown in the given image.

Classification of Phenol

We get phenol by substituting OH group in place of H in benzene ring. It can be classified into three types:

• Monohydric phenols: These phenols contain one -OH group.  (e.g. o,m,p- cresol)

• Dihydric phenols: They contain two -OH groups. They could be either ortho-, meta- or para- derivative.  (e.g. Resorcinol)

• Trihydric phenols: They contain three -OH groups.  (e.g. benzene 1,3,5- triol)
