Question

Tca has greater acidity than acetic acid. Bcos of EAIE of 3 cl increases the positivity of carbonyl C making release of proton easier. Please explain. Why Cl increases positivity when Cl is infact an electronegative element

Answer 1

Since Cl is so electronegativity, it is an electron withdrawing agent. That means it is pulling, through the inductive effect, electrons from elsewhere which makes the the carbonyl more positive and that helps release the proton.
