Concept explainers
(a)
Interpretation: The reason as to why electrophilic substitution occurs on the ring without
Concept introduction: The substitution reaction involves the replacement of one
(b)
Interpretation: The reason as to why electrophilic substitution occurs more readily at
Concept introduction: The substitution reaction involves the replacement of one functional group by other functional group. In nucleophilic substitution an electron rich species attack the species that is deficient in electrons. The electrophile and the leaving group together form a substrate. The nucleophile attacks over the substrate and there occurs the removal of leaving group from the substrate.
