Identify incorrectly matched set from the following

Options

  1. AMolecules with incomplete octet- BeH ₂, BCl ₃
  2. BPolar molecules- BF ₃, CCl ₄
  3. CMolecules with expanded octet- PCl ₅, SF ₆
  4. DOdd electron molecules-NO, NO ₂

Correct answer

B. Polar molecules- BF ₃, CCl ₄

Step-by-step solution

BF ₃ and CCl ₄ are non-polar molecules due to symmetrical arrangement of the bond pairs that result in the cancellation of the individual bond dipoles.
