Comment on solubility

Solubility of Carbon Tetrabromide

Carbon tetrabromide (CBr4) exhibits unique solubility properties, primarily influenced by its molecular structure and the nature of its interactions with solvents. This compound is:

  • Insoluble in water: Due to its non-polar characteristics, carbon tetrabromide does not dissolve in polar solvents like water.
  • S soluble in organic solvents: It readily dissolves in non-polar organic solvents such as benzene, ether, and chloroform. This is attributed to the similar non-polar nature of both the solute and the solvent.

In summary, the solubility behavior of CBr4 highlights the principle of "like dissolves like," where non-polar substances prefer to dissolve in non-polar solvents. This makes carbon tetrabromide a useful solvent in various organic chemistry applications.
