Select the two true statements.

A) An organic compound with a dipole moment absorbs all wavelengths of IR radiation equally.
B) Wavelength is proportional to the energy of a light wave.
C) IR absorption is caused by the interaction of the electric field of light with a vibrating bond dipole.
D) A necessary but not sufficient condition for IR absorption is a match between the frequency of the vibrational mode and the frequency of light.
E) A sufficient condition for IR absorption is a match between the frequency of the vibrational mode and the frequency of light.f.
Every IR absorption corresponds to the vibration of an individual bond.
