Which one of the following orders is correct regarding the inductive effect of the substituents?
Open in App
Solution
The correct option is C -NR2<-OR<-F
Relative inductive effects have been experimentally measured with reference to hydrogen, in decreasing order of -I effect or increasing order of +I effect, as follows:
–NH3+ > –NO2 > –SO2R > –CN > –SO3H > –CHO > –CO > –COOH > –COCl> –CONH2 >
–F > –Cl > –Br > –I > –OR > -OH > –NH2 > –C6H5 > –CH=CH2 > –H
From this, you can get the required answer.
