Question

Name the which group causes + I effect?​

Answer 1

Answer:

The polarization of a bond due to electron withdrawing or electron

donating effect of adjacent groups or atoms is called inductive effect.

Negative inductive effect (-I):  

The electron withdrawing nature of

groups or atoms is called as negative inductive effect. It is indicated by -I.

Following are the examples of groups in the decreasing order of their -I effect.Electron withdrawing groups are having negative inductive effect (-I)

NH  

3+

>NO  

2

​

 >CN > SO  

3

​

H>CHO>CO>COOH>COCl>CONH_2>F>Cl>Br>I>OH>OR>NH_2>C_6H_5$$

> H .

Hence options A,B are having -I Efferct.
