The products obtained from the given sequences of reaction has to be predicted. Concept introduction: Standard nucleophilic addition to a carbonyl group is 1 , 2 -addition. In the first step, nucleophile adds to carbonyl group to give alkoxide. Then, protonation of alkoxide takes place. 1 , 4 -addition is Michael addition. The nucleophile adds to beta carbon of α , β -unsaturated system to give enolate ion followed by protonation at oxygen to give an enol or on carbon to give a keto form.

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 products obtained from the given sequences of reaction has to be predicted.

Concept introduction:

Standard nucleophilic addition to a carbonyl group is 1,2-addition. In the first step, nucleophile adds to carbonyl group to give alkoxide. Then, protonation of alkoxide takes place. 1,4-addition is Michael addition. The nucleophile adds to beta carbon of α,β-unsaturated system to give enolate ion followed by protonation at oxygen to give an enol or on carbon to give a keto form.
