Question

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

Answer 1

The statement is true; weakly polar bonds produce weak bands in an IR spectrum because they have a small change in dipole moment when they vibrate.

Step-by-step explanation:

The statement 'Weakly polar bonds produce weak bands in an IR spectrum' is true. In Infrared (IR) spectroscopy, the intensity of the absorption bands is related to the change in the dipole moment of a molecule as it vibrates.

Weakly polar bonds have a small change in dipole moment when they vibrate, which translates to weaker absorption and consequently, weak bands in the IR spectrum. This is contrasted with strongly polar bonds that have a larger change in dipole moment when they vibrate, leading to more intense absorption bands.
