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 breaks.

Options

A. At specific composition methanol-acetone mixture will form minimum boiling azeotrope and will show positive deviation from Raoult’s law
B. At specific composition methanol-acetone mixture will form maximum boiling azetrope and will show positive deviation from Raoult’s law
C. At specific composition methanol-acetone mixture will form minimum boiling azeotrope and will show negative deviation from Raoult’s law
D. At specific composition methanol-acetone mixture will form maximum boiling azeotrope and will show negative deviation from Raoult’s law

Answer

A

Explanation

At specific composition methanol-acetone mixture will form minimum boiling azeotrope and will show positive deviation. This is due to weaker A - B interaction than A - A or B - B interaction. i.e., A - B `lt` A - A and B - B .
