How can we differentiate bent and linear structures for AB₂ molecules using IR spectroscopy? A) Bent structure will show both symmetric and antisymmetric vibrations, linear only antisymmetric. B) Linear structure will show both symmetric and antisymmetric vibrations, bent only symmetric. C) We cannot do conclusive differentiation without Raman spectroscopy.

Bent molecules have both symmetric and antisymmetric stretching vibrations that are IR active, while linear molecules have only antisymmetric stretching vibrations that are IR active because their symmetric stretches do not change the dipole moment.
