Which factors will increase the reactivity of ( C = O ) group? (i) Presence of a group with positive inductive effect (ii) Presence of a group with (-ve) inductive effect (iii) Presence of large alkyl group

Step-by-step solution

If (Z ) is ((-1) ) effect group, then reactivity will increases because such gp increases more partial the charge density on carboxyl carbon. Which inhances nucleophilic substitution (SN) reaction and nucleophilic addition reaction.
