IR Active Molecules
IR (Infrared) active molecules are those molecules that can absorb infrared radiation and undergo a change in their molecular vibrations or rotations. IR spectroscopy is a technique that is used to determine the functional groups present in a molecule and to identify the type of bonds present in a molecule.
Examples of IR Active Molecules
1. CO2 (Carbon Dioxide) - CO2 is a linear molecule with a symmetrical arrangement of atoms. It has two polar bonds, but the molecule itself is nonpolar. Therefore, it does not absorb IR radiation and is not IR active.
2. CS2 (Carbon Disulfide) - CS2 is a linear molecule with a symmetrical arrangement of atoms. It has a polar bond, but the molecule itself is nonpolar. Therefore, it does not absorb IR radiation and is not IR active.
3. OCS (Carbonyl Sulfide) - OCS is a linear molecule with a polar bond. The molecule is also polar due to the difference in electronegativity between the sulfur and oxygen atoms. Therefore, it absorbs IR radiation and is IR active.
4. N2 (Nitrogen) - N2 is a linear molecule with a nonpolar arrangement of atoms. It does not have any polar bonds, and the molecule itself is nonpolar. Therefore, it does not absorb IR radiation and is not IR active.
Conclusion
Based on the above explanation, the correct answer to the question is C) OCS. OCS is a polar molecule and has a polar bond, which makes it IR active. CO2, CS2, and N2 are nonpolar molecules and do not absorb IR radiation, making them not IR active.

For a molecule to be IR active, there should be transition dipole moment in molecule. It means if there there a change in dipole moment during any vibration, it is IR active. In Assymetric stretching, both a and b have a transition dipole moment. Thus their are IR active. NOTE: Permanent dipole moment is necessary for Microwave Spectroscopy.Transition dipole moment is necessary for IR Spectroscopy.
