Which of the following molecules has zero dipole moment?

Options

  1. AH ₂ O
  2. Bx ₂ H ₂ ~S
  3. CX ₃ NF ₃
  4. DCO ₂

Correct answer

D. CO ₂

Step-by-step solution

In CO ₂ , the C - O bond dipoles are equal in magnitude but oriented in opposite directions (at 180^ ). Their vector sum is zero, so CO ₂ has no net dipole.
