Answer to Question 1

During an aliphatic nucleophilic substitution by SN2 mechanism, a complete inversion in stereochemistry of a particular structure takes place. This stereochemical outcome is called Walden inversion. One such example is the conversion of L-malic acid into D-chlorosuccinic acid.

Answer to Question 2

-NH2 is a poor leaving group, but it is a good nucleophile because of the presence of lone pairs. The reaction between cyclohexylamine or aniline and methyl bromide helps in the formation of N-methylamines via an SN2 mechanism. Howev
