What is the action of CH3MgBr on propanone.
Answers
Answer:
Reaction of acetone (propanone) with grignard reagent (methyl magnesium bromide) result in the formation of tertiary butyl alcohol. CH3-Mg-Br + CH3-CO-CH3 ------> (CH3)3 -CO-Mg-Br -------->(hydrolysis takes place) (CH3)3C-OH+ Mg-Br-OH. Hope you understand.
Answer:
Propanone (acetone) on reaction with Grignard reagent (CH₃MgBr) gives tertiary alcohol.
Explanation:
What is Propanone?
Propanone is the simplest form of ketone also known as acetone, in its structure, the two alkyl groups are attached to the carbonyl group.
What are Grignard reagents and their properties?
In organic chemistry, it is widely used to expand the carbon chain. its formula is RMgX, where R - Alkyl group, Mg- Magnesium, X- Halogens (Cl, Br, and I).
- it can be basic in nature because of its alky group's high electron density.
- it acts as a strong nucleophile.
- it must be stored in a dry atmosphere.
Grignard reagents react with Formaldehyde, other aldehydes, and ketones to give primary alcohol, secondary alcohol, and tertiary alcohol, respectively.
How does Propanone react with CH₃MgBr?
The nucleophilic addition of RMgX to the carbonyl group initiates this reaction, which is followed by hydrolysis to yield 3⁰ alcohol.
