SECTION - A

Which one of the following pairs will form an ideal solution?

chloroform and acetone
ethanol and acetone
n-hexane and n-heptane
phenol and aniline

Solution:

n-hexane and n-heptane will form an ideal solution over entire range of concentrations as their intermolecular interactions (solutesolvent) after forming solution are similar to their intermolecular attractions (solute-solute, solventsolvent) before mixing the components.
