On the basis of information given below mark the correct option. Information : On adding acetone to methanol some of the hydrogen bonds between methanol molecules break.

Answer»

At specific composition, methanol - ACETONE mixture will form minimum boiling AZEOTROPE and will show positive deviation from Raoult's law
At specific composition, methanol-acetone mixture forms maximum boiling azeotrope and will show positive deviation from Raoult's law
At specific composition methanol-acetone mixture will form minimum boiling azeotrope and will show NEGATIVE deviation from Raoult's law
At specific composition methanol-acetone mixture will form maximumboiling azeotrope and will show negative deviation from Raoult's law

Solution :As hydrogen BONDS break, vapour pressure will be higher, i.e. it wll show `+ve` it will show `+ve` deviation from Raoult's law and form a minimum boiling azeotrope.
