Answer 2

Phenol on treatment with CH₃MgBr gives a mixture of an alkane and magnesium alkoxide.

• Haloalkanes and other haloalkyl compounds with the halogen atom attached to carbon atoms (aryl or vinyl halides) react with magnesium metal to yield Grignard reagents (R-Mg-X).
• Both alcohols and phenols form alkanes and magnesium alkoxide on treatment with Grignard reagents.
• R-OH + R'-MgX → R'-H + Mg(OR)X
• Thus, the alkane formed in this reaction corresponds to the alkyl group of the Grignard reagent used in the reaction.

So, when phenol (C₆H₅OH) reacts with CH₃MgBr it gives a mixture of

C₆H₅OH + CH₃MgBr → CH₄ + Mg(OC₆H₅)Br
