Which factors will increase the reactivity of ( C=O ) group? (i)...

Which factors will increase the reactivity of (C=O\mathrm{C}=\mathrm{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 groupWhich factors will increase the reactivity of ( C=O ) group? (i) Presence of a group with positive inductive effect

Options

  1. AOnly (i)
  2. BOnly (ii)
  3. CBoth (i) & (iii)
  4. DBoth (ii) & (iii)

Correct answer

B. Only (ii)

Step-by-step solution

Which factors will increase the reactivity of ( C=O ) group? (i) Presence of a group with positive inductive effect
If ZZ is (−1)(-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.
