Ques. 1NEET 2016 (Phase 2)

Among the following, which one is a wrong statement ?

  1. PH5 and BiCl5 do not exist.
  2. p -d bonds are present in SO2.
  3. SeF4 and CH4 have same shape.
  4. I3+ has bent geometry.

Answer

(3) SeF4 and CH4 have same shape.

Solution

(1) Correct: PH5 is not formed (H cannot make P use its d-orbitals) and BiCl5 is not formed (inert pair effect ⇒ +3 state of Bi is stable).

(2) Correct: SO2 has one p -p and one p -d bond.

(3) Wrong: SeF4 ⇒ 4 bp + 1 lp, sp3d ⇒ see-saw; CH4 ⇒ 4 bp, sp3 ⇒ tetrahedral.

(4) Correct: I3+ ⇒ central I has 2 bp + 2 lp, sp3 ⇒ bent.

Answer: (3)
