How do you determine the molecule is microwave active or inactive?

Answer 1

It is determined by whether the molecule is polar or nonpolar. Nonpolar molecules do not absorb radiation in the microwave region; therefore, they are microwave inactive. Polar molecules are microwave active.

Answer 2

A molecule is considered microwave active if it has a net dipole moment resulting from the uneven distribution of charges within the molecule. This uneven distribution causes the molecule to rotate and absorb microwave radiation. In contrast, molecules that are symmetric and have a zero net dipole moment are considered microwave inactive because they do not interact with microwave radiation.

Answer 3

For a molecule to be micro wave active.......there should be change in dipole moment of the molecule....
