A molecular model representing a tetrahedral intermediate that results from the addition of a nucleophile to an aldehyde or ketone is given. The reactants are to be identified and the structure of the final product obtained on completion of the reaction is also to be shown. Concept introduction: Primary amines react with aldehydes and ketones to yield imines R 2 C=NR while secondary amines react to yield enamines R 2 NCR=CR 2 . Both reactions are typical examples of nucleophilic addition reactions in which water is eliminated from the intermediate initially formed leading to the formation of a new C=Nu double bond. To identify: The reactants, a nucleophile and an aldehyde or ketone that give the tetrahedral intermediate in an addition reaction. Further to show the structure of the final product obtained on completion of the reaction.

Question

Where are the chiral centers in this molecule? Also is this compound meso yes or no?

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:

A molecular model representing a tetrahedral intermediate that results from the addition of a nucleophile to an aldehyde or ketone is given. The reactants are to be identified and the structure of the final product obtained on completion of the reaction is also to be shown.

Concept introduction:

Primary amines react with aldehydes and ketones to yield imines R₂C=NR while secondary amines react to yield enamines R₂NCR=CR₂. Both reactions are typical examples of nucleophilic addition reactions in which water is eliminated from the intermediate initially formed leading to the formation of a new C=Nu double bond.

To identify:

The reactants, a nucleophile and an aldehyde or ketone that give the tetrahedral intermediate in an addition reaction. Further to show the structure of the final product obtained on completion of the reaction.
