Question

how does acetone react with CH3MGBR

Answer 1

he Grignard reagent features a more or less direct bond between a carbon centre and a metal centre: RH2Cδ−+δMgX, or even as a full-blown carbanion, RH2C−+MgX. Given this formulation, its interaction with a carbonyl species may be rationalized.

The Grignard will react with an aldehyde to form (after workup) a 2∘ alcohol, with a ketone to give a 3∘ alcohol, with carbon dioxide, and ethylene oxide, to give a carboxylic acid, or a primary alcohol respectively. All of these are examples of prized C−C bond forming reactions.

Answer 2

Acetone reacts with methyl magnesium bromide to form 2 -methyl 2 propanol and magnesium hydroxy bromide .

Explanation:

Acetone

It is the first member of ketone with formula CH₃COCH₃

Grignard reagent

It is a famous chemical compound with formula either alkyl magnesium bromide or phenyl magnesium bromide .

For example : In this case it is CH₃MgBr(methyl magnesium bromide ).

Reaction between Acetone and grignard reagent

Ketone has a double bond that is between CO therefore , it shows addition kind of reaction that leads to formation of an intermediate.

Then this intermediate is hydrolyzed in acidic medium and it forms 2-methyl 2 propanol and magnesium hydroxy bromide .
