The observation, Grignard reaction of cyclohexanone with tert -butylmagnesium bromide yields only about 1% of the expected addition product along with 99% unreacted cyclohexanone. If D 3 O + is added to the reaction mixture after a suitable period, however, the unreacted cyclohexanone is found to have one deuterium atom incorporated into it, is to be explained. Concept introduction: Grignard reagents add to the carbonyl group in aldehydes and ketones . The addition product when hydrolyzed with aqueous acids yields a secondary alcohol in the case of aldehydes other than formaldehyde and a secondary alcohol in the case of ketones. Ketones exist in acid catalyzed reversible equilibrium with their enol tatomers.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Interpretation Introduction

Interpretation:

The observation, Grignard reaction of cyclohexanone with tert-butylmagnesium bromide yields only about 1% of the expected addition product along with 99% unreacted cyclohexanone. If D₃O⁺ is added to the reaction mixture after a suitable period, however, the unreacted cyclohexanone is found to have one deuterium atom incorporated into it, is to be explained.
