The I2 molecules in iodine and the CCl4 molecules in carbon tetrachloride are both held together by weak intermolecular bonds. Similar intermolecular bonds can form between I2 and CCl4 molecules in a solution of I2 in CCl4. I2 therefore readily dissolves in CCl4. The molecules in water are held together by hydrogen bonds that are stronger than most intermolecular bonds. No interaction between I2 and H2O molecules is strong enough to compensate for the hydrogen bonds that have to be broken to dissolve iodine in water, so relatively little I2 dissolves in H2O making it aqueous solution.
