Among LiCl , BeCl ₂, BCl ₃ and CCl ₄ , the covalent bond character follows the order

Options

  1. ALiCl BeCl ₂ BCl ₃ CCl ₄
  2. BBCl ₃ CCl ₄ BeCl ₂ LiCl
  3. CBeCl ₂ LiCl CCl ₄ BCl ₃
  4. DCCl ₄ BCl ₂ BeCl ₂ LiCl

Correct answer

A. LiCl BeCl ₂ BCl ₃ CCl ₄

Step-by-step solution

Covalent character increases with decrease in the value of difference in electronegativites of binding atoms. Thus, the correct order is LiCl BeCl ₂ BCl ₂ CCl ₄
