Solution

Bromine:

  1. Bromine is chemically represented by the symbol Br.
  2. It has an atomic number of 35.

Dissolved in CCl4 or Water:

  1. Slowly, Bromine interacts with C-H bonds by substituting free radicals.
  2. Due to its inability to react with bromine, CCl4 solvent enables long-term storage of bromine solutions.
  3. Bromohydrin is formed with the aid of water, which helps to add Br and 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 (Br2)-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 (CCl4) is widely used.

Hence, Bromine is used when dissolved in CCl4 or water.
