Question

The product of the following reaction is P . The number of hydroxyl groups present in the product P is________.

TestHub · Accepted Answer

The reaction proceeds via addition of Grignard's reagent ( $PhMgBr$ ).

A Grignard reagent is an organomagnesium compound which can be described by the chemical formula ‘R-Mg-X’ where R refers to an alkyl or aryl group and X refers to a halogen.

When $C_{6} H_{4} CHOOH$ reacts with grignard's reagent benzene along with an addition product is formed, which on further reaction with aq ammonium chloride gives $C_{6} H_{4} CHOOH$ .

Here ${Ph}^{-}$ is a strong base which is extracting proton from the reactant to give benzene.

The reaction is as follows,

Product P is benzene and it has zero hydroxyl group.
