(a) Two volatile counpunds differ in their boiling points by 20 K, how will they be separated?
(b) What types of compounds are purified by sublimation?

Text Solution

Verified by Experts

(a). Fractional distillation.
(b). Substances whose vapour pressure become equal to the atmospheric pressure much below their boiling points.
(c). Either by sublimation or by extraction with `C Cl_4` followed by evaporation
(d) `o-` Nitrophenol is stream volatile while `p-` nitrophenol is not hence they are separated by steam distillation.
(e). Vacuum distillation or steam distillation.
(f). By simple distillation.
