(a) Volatile

(b) Non-Volatile

(c) Cryogenic

(d) None of the mentioned

I had been asked this question by my college director while I was bunking the class.

This interesting question is from Distillation-Vapour Liquid Equilibria topic in division Distillation of Mass Transfer

Answer 1

Right answer is (b) Non-Volatile

To explain I would say: There is no boiling point for the Non-volatile compound. So the sugar has no vapour pressure.
