Question

How allyl alcohol is prepared using grignard reagent

Answer 1

Answer:

Grignard reaction is a simple method that can produce primary, secondary and tertiary alcohol. For a primary alcohol to be produced, the Grignard reagent is mixed or reacted with formaldehyde.

Grignard reagent when mixed with other aldehyde will produce a secondary alcohol and if react or mixed with a ketone will produce a tertiary alcohol.  

The chemical reaction is as follows:

CH3MgBr(Grignard reagant) + Acetone == Allyl (t-butyl) Alocohol + MgBrCl  

Answer 2

The Grignard reaction is the only viable simple method that can produce principal, secondary and tertiary alcohols.

• The Grignard reagent is reacted with formaldehyde in order to produce a primary alcohol.
• Reacting with any other aldehyde to a Grignard reagent will result in a secondary alcohol.  
• A tertiary alcohol is generated by the reaction of a Grignard reagent with a ketone.
• The reaction that takes place is - CH3MgBr(Grignard reagant) + Acetone → Allyl (t-butyl) Alcohol + MgBrCl
