A mechanism that gives the products for each reaction is to be written. Concept introduction: Electrophiles are electron deficient species that have positive or partially positive charge. Lewis acids are electrophiles that accept electron pair. Nucleophiles are electron rich species that have negative or partially negative charge. Lewis bases are nucleophiles that donate electron pair. Free radical is an atom, molecule, or ion that has an unpaired electron, which makes it highly chemically reactive. Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any other functional group is called substitution reaction.

Interpretation Introduction

Interpretation:

A mechanism that gives the products for each reaction is to be written.

Concept introduction:

Electrophiles are electron deficient species that have positive or partially positive charge. Lewis acids are electrophiles that accept electron pair.

Nucleophiles are electron rich species that have negative or partially negative charge. Lewis bases are nucleophiles that donate electron pair.

Free radical is an atom, molecule, or ion that has an unpaired electron, which makes it highly chemically reactive.

Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any other functional group is called substitution reaction.

Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.

Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules.

In Michael reaction, the conjugate addition of α,β− unsaturated carbonyl compounds takes place.

If the nucleophile is weak, then the conjugate addition is favored.

Base removes acidic hydrogen and forms the enolate ion.

The enolate adds to the β− carbon of α,β− unsaturated carbonyl compound and results in the formation of a new enolate.

Protonation of the enolate results in the formation of the final product.
