rue or False 1. Sample preparation of infrared spectroscopy uses KBr as the blank because Kbr has 100% transmittance at the IR wavelength range. 2. The electronegativity difference present in a dipole moment within a bond is directly proportional to the electromagnetic field produced. 3. The electromagnetic radiation that is emitted in infrared spectroscopy is not enough to excite electrons to an unoccupied molecular orbital.

Stereochemistry and Isomerism

Stereochemistry deals with the three-dimensional structure and properties of molecules. It explains the arrangement of atoms and their manipulation within a molecule in a 3D structure. Stereochemistry can be dealt with all types of molecules. Based on the stereochemistry of a molecule, the physical and chemical properties of the molecules vary.
