Answer 1

When phenol is added to the aniline, it shows the negative deviation.

Let's discuss first what is a negative deviation

If the partial vapor pressure of a solution is lesser than the solution of the same compound. For example phenol and aniline

In a mixture of phenol and aniline, it shows a negative deviation because of the intermolecular bonding between proton of phenol and lone pair present on the nitrogen atom are stronger than corresponding intermolecular hydrogen bonding between the same composition.
