Question

When phenyl magnesium bromide reacts with tert-butanol, the product would be

• A. Benzene
• B. Phenol
• C. tert-butylbenzene
• D. tert-butyl phenyl ether

Answer 1

The correct option is A Benzene

Grignard reagents are extremely useful organometallic compounds in the field of organic chemistry. They exhibit strong nucleophilic qualities and also have the ability to form new carbon-carbon bonds. Therefore, they display qualities that are also exhibited by organolithium reagents and the two reagents are considered similar. 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.

Grignard reagents react with compounds containing active hydrogen to form hydrocarbons corresponding to alkyl (or aryl) part of the Grignard reagent.
$C_6{H}_{5}MgBr+M{e}_{3}COH\to C_6{H}_6+M{e}_{3}COMgBr$

Hence, the correct answer is option (a).
