Question

Ethyl alcohol cannot be used as a solvent for methyl magnesium iodide because

• A. methyl magnesium iodide reacts with alcohol giving methane
• B. the reaction between them is explosive in nature
• C. methyl magnesium iodide is converted to ethyl magnesium iodide
• D. alcohol is immiscible with methyl magnesium iodide

Answer 1

Answer: (A)

methyl magnesium iodide reacts with alcohol giving methane

Answer 2

Methyl magnesium iodide (Grignard reagent) readily gives alkane when reacts with a protonic compound like ethyl alcohol.
$C _{2} H _{5} OH + CH _{3} Mgl \rightarrow \underset{\text{methane}}{CH _{4}}$
Because of the above reason, ethyl alcohol cannot be used as a solvent for methyl magnesium iodide.
