Question

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.

• 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 azeotrope 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 1

The correct option is A At specific composition methanol-acetone mixture will form minimum boiling azeotrope and will show positive deviation from Raoult's law

On adding acetone to methanol some of the hydrogen bond breaks and the interactions between the methanol and ethanol decreases, so it show minimum boiing azeotrope and show positive deviation from Raoult's law.
