Observe the following statements: i. According to VSEPR theory, ( ClF ₃ ) and ( SO ₂ ) are shown (A B₃ E ) and (A B₂ 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

  1. Ai, ii only
  2. Bi, iii only
  3. Ci, ii, iii
  4. Dii, iii only

Correct answer

B. i, iii only

Step-by-step solution

Statements (i) and (iii) are not correct. Their correct explanation are as follows: (i) According to VSEPR theory ( ClF ₃ ) has 3 bond pairs and 2 lone pairs thus it is (A B₃ E₂ ) type molecule whereas ( SO ₂ ) has (2 ) bond pairs and one lone pair so it is (A B₂ 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.
