Vedclass · Answer

(B) In a mixture of $n$-heptane and ethanol,the intermolecular forces between $n$-heptane and ethanol molecules are weaker than the forces between $n$-heptane$-n$-heptane molecules and ethanol-ethanol molecules.Due to the presence of hydrogen bonding in pure ethanol,the $n$-heptane molecules disrupt these interactions.As a result,the total vapor pressure of the solution is higher than that predicted by Raoult's Law.Therefore,the solution is non-ideal and shows a positive $(+ve)$ deviation from Raoult's Law.

$A$ binary liquid solution is prepared by mixing $n$-heptane and ethanol. Which one of the following statements is correct regarding the behaviour of the solution?
