Inductive effect
Order of the power of -I groups?
This is the order my sir gave and I found the same online:
NH₃⁺ > NO₂ > CN > SO₃H > CHO > CO > COOH > COCl > CONH₂ > F > Cl > Br > I > OH > OR > NH₂ > C₆H₅ > H

But OP Tandon shows COCl > CHO > CO

Which one is correct? Help? Thanks in advanced.

Vikas TU · Answer

First one! Acid chloride cannot have more -I effect than aldehyde and ketone. as Inductive effect is the distance dependent and to shows -I effect chlorine charge has to cover a distance which is more than in aaldehyde and keto group .
