The reaction sequences that explain the given transformations are to be stated. Concept introduction: In acid-catalysed Aldol condensation, nucleophilic addition of an enol takes palce at a protonated carbonyl group. In the first step, enol is formed when carbonyl oxygen gets protonated. Then, deprotonation occurs at alpha carbon. In the next step, enol adds to the protonated carbonyl followed by deprotonation to give the aldol product

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 reaction sequences that explain the given transformations are to be stated.

Concept introduction:

In the claisen-ester condensation, neucleophilic acyl substitution takes place on an ester. The enolate ion acts as a neucleophile. It attacks the carbonyl carbon to form a tetrahedral intermediate. Acidity of beta-keto ester products is higher than simple ketones, aldehydes and esters.
