what types of intermolecular bonding is present in water methyl benzene and oleic acid. and how would these bonds explain the differences in time taken for the vortex to dissapear in each liquid?

in water strong intermolecular H-bonding are present (thats the reason water has a high boiling point)
mostly whenever the hydrogen is attached to a highly electronegative atom for eg oxygen, nitrogen etc.
hence even oleic acid will have hydrogen bonding but due to the hydrocarbon chain that leads to a lot of crowding up(known as sterric hindrance)the h-bonding is less.
in the case of methyl benzene there are no dipoles present (i.e. absence of any difference in electronegativity )hence the only forces present are due to momentatrily induced dipole due to electron spins most ussually these are reffered to as vanderwaals force, london force or dispersion force

In water there are strong hydrogen bounds. This explain the peculiarity of water where the liquid is more dense than the solid (ice)
In oleic acid , as there is a group COOH, there should be also hydrogen links weaker than in water
In methyl benzene an apolar molecule there should only exist hydrophobic forces
