Identify a molecule with incomplete octet from following.

Options

  1. ASF ₆
  2. BPCl ₅
  3. CLiCl
  4. DH ₂ SO ₄

Correct answer

C. LiCl

Step-by-step solution

Li in LiCl has less than eight electrons in its valence shell. It has only four electrons. Hence, it has an incomplete octet. Molecules like SF ₆ , PCl ₅, H ₂ SO ₄ have an expanded octet. They have more than eight electrons around the central atom.
