Which of the following binary mixture does not show the behaviour...

Which of the following binary mixture does not show the behaviour of minimum boiling azeotropes?

Options

A $\mathrm{H}_2 \mathrm{O}+\mathrm{CH}_3 \mathrm{COC}_2 \mathrm{H}_5$
B $\mathrm{C}_6 \mathrm{H}_5 \mathrm{OH}+\mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2$
C $\mathrm{CS}_2+\mathrm{CH}_3 \mathrm{COCH}_3$
D $\mathrm{CH}_3 \mathrm{OH}+\mathrm{CHCl}_3$

Correct answer

B. $\mathrm{C}_6 \mathrm{H}_5 \mathrm{OH}+\mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2$

Step-by-step solution

Binary mixture of

\mathrm{C}_6 \mathrm{H}_5 \mathrm{OH}

and

\mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2

shows negative deviation from Raoult's law
So vapour pressure of solution is less than V.P of pure

\mathrm{C}_6 \mathrm{H}_5 \mathrm{OH} \& \mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2

So B.P. of solution is greater than boiling point of pure

\mathrm{C}_6 \mathrm{H}_5 \mathrm{OH} \& \mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2

So shows maximum Boiling azeotrope
