Like dissolves Like principle used in the solubilty i.e non
polar compounds are soluble in non polar solvents and polar
compounds are soluble in polar solvents
A) C6H12 = which is called as hydrocarbon i.e cyclohexane and it is non polar so it is soluble in CCl4
B) Cu(NO3)2 = which is ionic compound and it is soluble in polar solvents and not soluble in non polar solvents
C) Br2 = it is non polar and it is dissolved in soluble in CCl4
D) C3H8 = which is called as hydrocarbon i.e propane and it is non polar so it is soluble in CCl4
E) I2 = it is non polar and it is dissolved in soluble in CCl4
answer => B is not soluble i.e immiscible in CCl4
