Question

True or False? Strongly polar bonds produce weak bands in an IR spectrum a) True b) False

Answer 1

Strongly polar bonds typically cause strong, well-defined absorption bands in an IR spectrum, hence the statement is false.

Step-by-step explanation:

The statement that strongly polar bonds produce weak bands in an IR spectrum is false. In infrared (IR) spectroscopy, the intensity of the absorption bands is related to the change in dipole moment during the vibration of the molecule.

Strongly polar bonds generally have a significant change in dipole moment when they vibrate, leading to strong, well-defined absorption bands in the IR spectrum. Conversely, weakly polar bonds or nonpolar bonds may produce weaker bands because there is little to no change in dipole moment during their vibration.
