A) filtration
B) distillation
C) crystallization
D) sublimation
Correct Answer: B
Solution :
Simple distillation can be used for the separation and purification of a mixture of two or more miscible organic liquids which are sufficiently stable at their boiling points and their boiling points differ by\[30-50\,\,K\]. The more volatile liquid distils over first while the less volatile liquid distils over afterwards. For example, mixture of ether \[(b.p.308\,\,K)\] and benzene \[(b.p.353\,\,K)\] can be separated by simple distillation.
