Original Khojo Papers practice question — not from a past board paper.
Answer
The inductive effect is the permanent displacement of the electrons of a sigma bond towards the more electronegative atom, transmitted with diminishing strength along the chain; the chlorine in chloroacetic acid withdraws electrons and makes it a stronger acid than acetic acid. The resonance effect is the delocalisation of pi electrons over more than two atoms; the carboxylate ion is stabilised by resonance, which is why carboxylic acids are acidic.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The inductive effect works through sigma bonds, the resonance effect through pi systems.
