Which of the following represents the correct order of densities?
A.CCl4>CHCl3> CH2Cl2> CH3Cl > H2O
B.CCl4>CHCl3> CH2Cl2> H2O > CH3Cl✓ Correct
C.H2O > CH3Cl > CH2Cl2>CHCl3>CCl4
D.CCl4>CHCl3> H2O > CH2Cl2> CH3Cl
Explanation
4 3 2 2 2 3 CCl >CHCl >CH Cl >H O>CH Cl Bromo, iodo and polychloro derivatives of hydrocarbons are heavier than water. The density increases with increase in number of chlorine atom, halogen atom but monochloro derivatives are lighter than water.
