Answer :
The reaction of 4-bromotoluene with a Grignard reagent would result in the formation of toluene [methylbenzene].
Here's a reaction scheme for the formation of toluene from 4-bromotoluene using a Grignard reagent:
Start with 4-bromotoluene (BrC₆H₄CH₃).
Add magnesium (Mg) and an ether solvent (like diethyl ether or THF) to form the Grignard reagent: 4-tolylmagnesium bromide (MgBrC₆H₄CH₃).
Add water (H₂O) to the Grignard reagent, which will initiate the nucleophilic addition of a hydride ion (H⁻) to the 4-position of the toluene ring.
The final product is toluene (C₆H₅CH₃).
