Current Question (ID: 18067)

Question:

$\text{The mixture that shows positive deviation from Raoult's law is-}$

Options:

1. $\text{Benzene + Toluene}$
2. $\text{Acetone + Chloroform}$
3. $\text{Chloroethane + Bromoethane}$
4. $\text{Ethanol + Acetone}$

Solution:

$\text{Hint: When A-A and B-B interaction is not equal to A-B interaction, then deviation in Raoult's Law occur.}$ $\text{In positive deviation from Raoult's Law, the resulting solution has more vapour pressure than the ideal solution of the constituent liquids.}$ $\text{This is because the A-B interactions are weaker than A-A \& B-B ones. Because there is hydrogen bonding present in the ethanol solution and acetone molecules tend to occupy the space between them due to which some hydrogen bonds breaks, results in weakening of A-B interaction.}$
