In order to understand what is the limiting reactant is useful to convert the masses of reactants into moles. The molecular masses are:
Converting masses into moles:
In the reaction, 2 moles of
are necessary to react with 1 mol of 
. Following this ratio:
We have only 0.5 mol of, i.e, we don't have enough amount of salicylic acid, therefore, this is the limiting reactant.
Converting masses into moles:
In the reaction, 2 moles of
We have only 0.5 mol of

Answer:
Order of increasing strength of intermolecular attraction:
>
>
> Ar
Explanation:
can form hydrogen bond as H atom is attached with electronegative atom O.
Rest three, ,
, Ar are non-polar molecules.
In non-polar molecules, van der Waal's intermolecular forces of attractions exist. Hydrogen bonding is stronger intermolecular attraction then van der Waal's intermolecular forces of attraction, hence, has strongest intermolecular attractions.
Ar will have least intermolecular attraction, as it behaves almost as ideal gas and there is no intermolecular attraction exist between molecules of ideal gases.
Molecular size and mass of is high as compared to
.
van der Waals intermolecular forces of attraction increases with increase in size.
Therefore,
Order of increasing strength of intermolecular attraction will be:
>
>
> Ar
