Why fluorine does not show variable valency while other halogens show variable valency?
Asked by Topperlearning User | 07 Jun, 2016, 11:04: AM
Expert Answer
Fluorine is the most electronegative element and cannot exhibit any positive oxidation state. Other halogens have d orbitals and therefore, can expand their octets and show + 1, + 3, + 5 and + 7 oxidation states also.
