Interpretation: The mechanism of given nucleophilic substitution reaction is to be determined and the products, along with their stereochemistry, are to be drawn.
Concept introduction: The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The electron rich chemical species that contains negative charge or lone pair of electrons are known as a nucleophile. In a nucleophilic substitution reaction, nucleophile takes the position of leaving group by attacking the electron deficient carbon atom.
Answer to Problem 7.63P
The mechanism of given nucleophilic substitution reaction is
Explanation of Solution
The structure of the given alkyl halide shows that a carbon atom, on which bromine atom is present, is bonded to two other carbon atoms. Hence, the bromine atom is bonded to secondary carbon atom. The removal of bromine atom leads to the formation of secondary carbocation. The secondary carbocation can undergo nucleophilic substitution reaction through both

The mechanism of given nucleophilic substitution reaction is
Explanation of Solution
The structure of the given alkyl halide shows that carbon atom, on which bromine atom is present, is bonded to three other carbon atoms. Hence, the bromine atom is bonded to tertiary carbon atom. The removal of bromine atom leads to the formation of planer tertiary carbocation. The tertiary carbocation is most likely to undergo nucleophilic substitution reaction by
