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.

Question

What is the lone pair or charge that surrounds the nitrogen here to give it that negative charge?

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.
