Question

decreasing order of +I effect​

Answer 1

Answer:-

Relative inductive effects have been experimentally measured with reference to hydrogen, in increasing order of −I effect or decreasing order of +I effect, as follows: –NH3+ > –NO2 > –SO2R > –CN > –SO3H > –CHO > –CO > –COOH > –COCl > -CONH2 >-F > –Cl > –Br > –I > –OR > -OH > -NR2 > –NH2 > –C6H5 > –CH=CH2 > –H.

Or you write this answer....

ANSWER

The decreasing order of -I effect is

I.R

4

N

⊕

>II.NO

2

>III.CN>IV.SO

3

H>V.COOH

As the magnitude of the positive charge on an atom decreases, the -I effect decreases.
