Answer:

The best options are "C & D"

C: The Grignard reagent is an example of an organometallic compound.

D: Once prepared, a Grignard reagent should be used quickly

Step-by-step explanation:

Grignard reagent is a highly reactive organomagnesium compound formed by the reaction of a haloalkane with magnesium in an ether solvent.Grignard reagents are useful for forming carbon–heteroatom bonds.

With formula RMgX

X is a halogen and R is an alkyl or aryl.

Answer: A and C

Explanation :

Grignard reagent are organometallic compound

formed as a result of the reaction between magnesium and an organic halide. They have the general formular RMgX.

Grignard reagent decompose rapidly upon reaction with water, thats why di-ethyl ether or tetrahydrofuran are used instead ,because the oxygen present in this solvent brings stability to magnesium .

It also act as a bronsted base for protic substrate. Grignard reagent are very good nucleophiles that react with electrophiles such as epoxide and carbonyl compounds.
