Question

suggest a method to purify benzene containing nonvolatile impurities ​

Answer 1

Answer:

For purifying benzene from a mixture that also contains non-volatile compounds, one can use the method of simple distillation.

In this technique, initially the solution needs to be heated till it reaches the boiling point of benzene, i.e., 80 °C.

Thereafter the vapors are allowed to pass through the tube till it reaches the condenser, where the vapors are cooled and allowed to liquefy again. The process is continued till no more vapors are formed.
