Explanation / Answer

MgCl2 is highly soluble in water since it's an ioniccompound. Ionic compounds are soluble in polar solvents, especiallythose that ionize, like water. Since ammonia is a polar compound, it's insoluble in benzene. H2 gas is slightly soluble in soluble. I2 is soluble in Br2. Like dissolves like. Both are non-polar. Thedipole-dipole interactions are strong enough to break the weaknonpolar bonds that hold nonpolar molecules together.
