Observe the following statements :
i. According to VSEPR theory, `CIF_(3)` and `SO_(2)` are shown `AB_(3)E` and `AB_(2)E` type molecules respectively.
(ii). `SF_(4)` has "See-saw" shape.
iii. `HgCl_(2)` and `PbCl_(2)` have same shape.
The statements which are not correct are

Options

A. i,ii only
B. i , iii only
C. i , ii, iii
D. ii, iii only

Answer

B

Explanation

Statements (i) and (iii) are not correct. Their correct explanation are as follows :
(i) According to VSEPR theory `CIF_(3)` has 3 bond pairs and 2 lone pairs thus it is `AB_(3)E_(2)` type molecule whereas `SO_(2)` has `2 sigma` bond pairs and one lone pair so it is `AB_(2)E` type molecule.
(iii) `HgCl_(2)` has a linear shape because it has 2 bond pairs only whereas `PbCl_(2)` has 2 bond pairs with one lone pair thus it has a bent shape.
