Which of the following compounds possesses zero dipole moment?
Which of the following compounds possesses zero dipole moment?
- A. \( H_{2} O \)
- B. \( C H_{3} F \)
- C. \( C C l_{4} \)
- D. \( B F_{3} \)
Step-by-step solution
Dipole moment is zero when bond dipoles cancel due to molecular symmetry. CCl4 has a tetrahedral geometry with four identical C-Cl bonds, so the vector sum of bond dipoles is zero. Additionally, BF3 also has zero dipole moment due to its trigonal planar symmetry, but CCl4 is a classic example.
