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

Correct Answer: A

Solution :

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