Question

Why is Bromine used when dissolved in ${\mathrm{CCl}}_4$ or water?

Answer 1

Bromine:

1. Bromine is chemically represented by the symbol $\mathrm{Br}$.
2. It has an atomic number of 35.

Dissolved in ${\mathrm{CCl}}_4$ or Water:

1. Slowly, Bromine interacts with $\mathrm{C}-\mathrm{H}$ bonds by substituting free radicals.
2. Due to its inability to react with bromine, ${\mathrm{CCl}}_4$ solvent enables long-term storage of bromine solutions.
3. Bromohydrin is formed with the aid of water, which helps to add $\mathrm{Br}$ and $\mathrm{OH}$ to the double bond.
4. The double bond is broken as a consequence, and the bromine atom attaches to each carbon atom.
5. During this process, bromine's dark brown color fades to white.
6. Vicinal dibromides are used to cure bromine (${\mathrm{Br}}_2$)-containing alkenes (1,2-Dibromides).
7. Bromine forms a double bond (anti-addition) on the opposing faces of the molecule.
8. In this process, the solvent is frequently addressed.
9. The solvent Carbon tetrachloride (${\mathrm{CCl}}_4$) is widely used.

Hence, Bromine is used when dissolved in ${\mathrm{CCl}}_4$ or water.
