Which of the following molecules is most suitable to disperse benzene in water                [AIIMS 2005]

A)                

B)                

C)                

D)                

Correct Answer: C

Solution :

           Benzene is non polar in nature. As we know that non-polar disperses more to non-polar substances. Therefore, meta-metyl nonylbenzene being nonpolar from both sides will disperse more to benzene. All other substances (a, b and d) have either one side polar or both sides polar.            \[\equiv {{H}_{19}}{{C}_{9}}-{{C}_{6}}{{H}_{4}}-C{{H}_{3}}\]
