In IR spectroscopy, the C-O bond has a ________ frequency than the C-N bond because ________.

A) higher; an O atom has more mass than an N atom
B) lower; an O atom has more mass than an N atom
C) higher; an O atom has more electronegativity than an N atom
D) lower; an O atom has more electronegativity than an N atom
E) higher; an O atom has an even number of neutrons

IR Spectroscopy

A technique used in analytical chemistry to identify molecular structure through the absorption of infrared radiation by molecules, leading to vibrational and rotational changes.

Electronegativity

A measure of the tendency of an atom to attract a bonding pair of electrons towards itself in a molecule.

Frequency

The number of occurrences of a repeating event per unit time.
