Question

how would you obtain primary, secondary and tertiary from grignard reagent, give reaction
​

Answer 1

Answer:

Grignard reaction with aldehydes and ketones

To produce a primary alcohol, the Grignard reagent is reacted with formaldehyde. Reacting a Grignard reagent with any other aldehyde will lead to a secondary alcohol. Finally, reacting a Grignard reagent with a ketone will generate a tertiary alcohol.
