Solubilty of components affect by polarity. Simlar substance
dissovle similar subtance. So polar substance dissolve polar substance and
nonpolar substance dissolves nonpolar substance. Since water is polar and
carbon tetracholride are non polar
Br2 dissolves in carbon tetracholride because it is non
polar
KF in water because it is polar
CH2O in water because it is polar
C6H14 is carbon tetracholride because it is non polar
