							A free-radical is defined as an atom or group of atoms which contains an unpaired electron.These are formed by homolytic cleavage of a covalent bond in presence of U.V light.Free-radicals are highly reactive species because of presence of one unpaired electron so they have tendency to share it with some other atom or group to complete its octet.For ex-alkyl free-radicals,chlorine free-radicals etc.
If we study the structure of alkyl free-radical we will found that C-carrying unpaired e- is sp2 hybridised.Three-sp2 hybridised orbitals are used in forming three sigma bonds with other atoms and the unpaired e- is present in the unhybridised p-orbital which is perpendicular to the plane of sigma-bonds.This unpaired e- makes the free-radical an paramagnetic species.So the option (b) is the correct answer.
