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
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.
