Questions: Some covalently bonded species do not obey the octet rule because they have an odd number of electrons. A species containing one electron is called a radical. Many radicals are highly reactive and tend to form a(n) bond with an unpaired electron on another molecule.

Solution Steps

A radical is a species that contains an unpaired electron. This occurs when there is an odd number of electrons in the molecule, which prevents all electrons from being paired. Radicals are often highly reactive due to the presence of this unpaired electron.

Radicals tend to form bonds with other molecules to achieve a more stable electronic configuration. The unpaired electron in a radical can pair with an unpaired electron from another molecule, forming a covalent bond. This type of bond is often referred to as a "single" bond, as it involves the sharing of one pair of electrons.
