A binary liquid solution of n-heptane and ethyl alcohol is prepared.Which of the following statements correctly represents the behaviour of this liquid solution?

$\begin{array}{1 1}\text{The solution formed is an ideal solution}\\\text{The solution formed is nonideal solution with positive deviations from Raoult's law}\\\text{The solution formed is nonideal solution with negative deviations from Raoult's law}\\\text{n-Heptane exhibits positive deviation whereas ethyl alcohol exhibits negative deviation from Raoult's law}\end{array} $

Answer : The solution formed is nonideal solution with positive deviations from Raoult's law
Escaping tendencies of both n-heptane and ethyl alcohol increase as compared to an ideal solution.The solution exhibits positive deviations from Raoult's law.This is due to less attraction between n-heptane and ethyl alcohol as compared to those existing separately between n-hyaptane and ethyl alcohol molecules
