 Q9: The mixture that forms maximum boiling azeotrope is:    (NEET 2019)

(a) Water + Nitric acid
(b) Ethanol + Water
(c) Acetone + Carbon disulphide
(d) Heptane + Octane

Ans: (a)

                                    

Maximum boiling azeotrope is shown by solution which shows negative deviation from Raoult's law. Except water + Nitric acid, all other mixtures show negative deviation.
