Question
Which of the following azeotropic solutions has the b.p. less than b.p. of the constituents A and B ?
Options
A.CHCl3 and CH3COCH3
B.CS2 and CH3COCH3
C.CH3CH2OH and CH3COCH3
D.CH3CHO and CS2
Solution
Mixtures of CH3CH2OH and CH3COCH3 shows positive deviation from Raoult′s law, so vapour pr. increases and b.p decreases.
