STANDARD Chemistry Dipole Moment MCQ Question
Which of the following, set of molecules will have zero dipole moment?
Ammonia, beryllium difluoride, water, 1, 4-dichlorobenzene
Boron trifluoride, hydrogen fluoride, carbon dioxide, 1, 3-dichlorobenzene
Nitrogen trifluoride, beryllium difluoride, water, 1,3-dichlorobenzene
Boron trifluoride, beryllium difluoride, carbon dioxide, 1, 4-dichlorobenzene
Correct Answer
Detailed Explanation
Boron trifluoride (BF₃), beryllium difluoride (BeF₂), carbon dioxide (CO₂), and 1,4-dichlorobenzene are all symmetrical molecules, which results in their dipole moments canceling out, leading to a net dipole moment of zero.
