Answer :
Final answer:
Methanol contains an -OH group that would react with the Grignard reagent, thus it is not a suitable solvent for Grignard reactions. So, the correct answer is option a) It reacts with the Grignard reagent.
Explanation:
Methanol is not a good solvent for a Grignard reagent because methanol contains an -OH group which is acidic and would react with the Grignard reagent. Grignard reagents are highly sensitive to protic solvents such as methanol because they can be protonated by the acidic hydrogen atoms present in the -OH group, leading to the degradation of the Grignard reagent and prevention of its intended reactivity. In this case, the correct answer is that methanol reacts with the Grignard reagent.
