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.

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 .

The order for -ve Inductive effect is as follows......NF3>NR3>NH3>CF3>NO2>CN>COOH>COCl>CONH2>CHO>COR>F>Cl>Br>I>OH>OR>NH2>triple bond>C6H5>double bond

NR3 will come first then NHR2 then SR2 And then NH3 all with a unipositive chrge...... Then comes NO2>-C[triplebond]N>aldehyde>ketone>carboxylic acid>f>cl>Br>I>CX3>Phenoxide ion>-OR>-OH>-NH2>Phenyl>Acetylene>Ethylene>H

Correct order

OP Tandon is not a good book for organic chemistry you should follow LG Wade. First order is correct which is given by your teacher

NMe3(positive charge over N) > NH3(positive charge over N)> NO2>CN>COOH>F>Cl>Br>I > OAr(Ar=benzene)>COOR> OR(R= Alkylegroup)>OH>C6H5>CH=CH2>H .........source - FIITJEE material
