Answer 1

Explanation:

Cyclobutyl bromide on treatment with magnesium in dry ether forms an organometallic compound (A). The organometallic compound reacts with ethanal to give an alcohol (B) after mild acidification.

Answer 2

When ethyl bromide reacts with magnesium metal in dry ether it forms Grignard's reagent.

Explanation:

• When ethyl bromide reacts with magnesium metal forms ethyl magnesium bromide
• $C2H5Br +Mg ------- C2H5MgBr$
• the reaction of Magnesium metal with ethyl bromide results in the formation of Ethyl magnesium bromide
• Ethyl magnesium bromide is also known as Grignard's Reagent.
• Grignard's reagent has a formula of RMgX.
• It is formed by the reaction of magnesium metal with Alkyl halide in the presence of dry ether.
• It is an important reagent that is used in Chemistry for the preparation of certain chemicals.
