Dipole moment order of which of the following pairs of molecules is not correct?

Options

  1. AHF > HCl
  2. BH ₂ ~S > CO ₂
  3. CNH ₃> NF ₃
  4. DCH ₄> CHCl ₃

Correct answer

D. CH ₄> CHCl ₃

Step-by-step solution

CH ₄ has a tetrahedral shape and is symmetrical so, its dipole moment is zero. But in CHCl ₃ presence of the one atom produce small dipole moment. Thus, dipole moment of chloroform is greater than methane.
