A solution of ethyl alcohol and water shows positive deviation from Raoult's law due to the presence of hydrogen bonding present in the ethyl alcohol solution and water molecules.

Chloroform $+$ carbon tetrachloride show positive deviation from Raoult's law Water $+ HCl$ is a non-ideal solution showing negative deviations from Raoult's law.

In a Benzene-toluene mixture, $A – B$ interactions are almost equal to $A – A$ and $B -B$ interactions due to the very small difference in the two compounds, i.e., they differ just by one $CH_2$ group. Hence, no deviation will occur from Raoult's law.
