Detailed explanation-1: -A free radical can be defined as an atom or molecule containing one or more unpaired electrons in valency shell or outer orbit and is capable of independent existence. The odd number of electron(s) of a free radical makes it unstable, short lived and highly reactive.
Detailed explanation-2: -Because of their high reactivity, they can abstract electrons from other compounds to attain stability. A few examples of free radicals are ethane, methane, singlet oxygen, ozone, and superoxide anion radicals.
Detailed explanation-3: -Moreover, there are two types of radicals: the sigma radicals and the pi radicals. An unpaired electron in the sigma-radical is in the sigma orbital and an unpaired electron in the pi radical is in the pi orbital respectively.
