WebJan 28, 2024 · A halogen (X) replaces a hydrogen in a compound because both form one single bond. Therefore the DoU formula subtracts the number of halogens (X) present in a compound. For instance, 1,1-dichloroethene (C 2 H 2 Cl 2) has two fewer hydrogens than ethene (C 2 H 4) yet they both have one degree of unsaturation. WebJan 25, 2024 · When two halogen atoms form a molecule, they form a covalent bond. Most compounds between the halogens and non-metals are also covalent. Fluorine is always univalent since it is the most electronegative element. Its oxidation number is always \ (-1\) with chlorine, bromine, and Iodine. A covalence of \ (1\) is the most common. Oxidation … reaction to hand sanitizer
