Azidoformates in which there is at least one group of the formula R -N ANGLE CH2CHOCON3 R1 attached to an aromatic nucleus, R representing an alkyl group of from 1 to 4 carbon atoms or a group of the formula -CH2CHOCON3 R1 and R1 representing hydrogen, chlorine, bromine, an alkyl ...
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...
