Benzene is a cyclic hydrocarbon with a chemical formula C6H6, that is, each carbon atom in benzene is arranged in a six-membered ring and is bonded to only one hydrogen atom. According to molecular orbital theory forbenzenestructure, benzene ring involves the formation of three delocalised π–...
Bromine, a halogen, forms the Br- anion when combined with a metal. In each formula unit of magnesium bromide, two Br- anions are required to balance the 2+ charge of the Mg2+ cation. The compound's formula must therefore indicate one Mg2+ cation and two Br- anions. The symbol for...
