What is a radical and why are they highly reactive?

Radicals are non-reactive due to their full electron shells.

A radical is a species with unpaired electrons, making it highly reactive.

Radicals are always negatively charged ions.

A radical is a stable molecule with paired electrons.

Explain the process of homolytic fission in halogens.

Homolytic fission occurs only in solid halogen compounds, not in gaseous diatomic molecules.

Homolytic fission in halogens involves the even breaking of a covalent bond in diatomic molecules, producing two free radicals.

Homolytic fission in halogens results in the formation of ionic compounds.

Homolytic fission involves the unequal breaking of a bond, creating one free radical and one stable molecule.
