Which of the following statements regarding Grignard reagents are TRUE? a. Grignard reagents tend to act as Bronsted bases. b. Grignard reagents decompose rapidly in anhydrous ether solutions. c. The Grignard reagent is an example of an organometallic compound. d. Once prepared , a Grignard reagent should be used quickly. e. A Grignard reagent contains electrophilic carbon. Tries 0/10

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.

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.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
