Which of the following has lowest dipole moment?

Question image

Understand the Problem

The question is asking which compound among the given options has the lowest dipole moment. We will analyze the molecular structures and electronegativities of the options provided to determine the answer.

Answer

CO2

The final answer is CO2, which has a dipole moment of zero due to its linear symmetry.

Answer for screen readers

The final answer is CO2, which has a dipole moment of zero due to its linear symmetry.

More Information

CO2, with its linear shape, has opposing dipoles canceling each other out, resulting in a zero dipole moment. This is unlike NF3, NH3, and NO2, all of which have inherent asymmetry causing non-zero dipole moments.

Tips

A common mistake is to assume that all molecules with polar bonds have dipole moments, but symmetry can lead to a net zero dipole moment.
