All the following liquid mixtures show negative deviations from Raoult’s law except

An azeotropic mixture of two liquids has a boiling point lower than either of the components when it

Which of them is not equal to zero for an ideal solution?&nbsp;

When two liquid components A and B are mixed to form an ideal solution, then the CORRECT statement is (VA and VB are volumes of the two components), Vsol = volume of the solution)

A solution of two components containing&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi>n</mi><mn>1</mn></msub></math>&nbsp;moles of the 1st component and&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi>n</mi><mn>2</mn></msub></math>&nbsp;moles of the&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><msup><mn>2</mn><mrow><mi>n</mi><mi>d</mi></mrow></msup></math>&nbsp;component is prepared.&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi>M</mi><mn>1</mn></msub></math>&nbsp;and&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi>M</mi><mn>2</mn></msub></math>&nbsp;are the molecular weights of component 1 and 2 respectively.
