Why toluene can be more easily nitrated than benzene ?

Out of phenol and benzene, which can be more easily nitrated ?

Nitration of benzene is

Nitration is an example of aromatic electrophilic substitution and its rate depends upon the group already present in the benzene ring. Out of benzene and phenol, which one is more easily nitrated and why ?

Benzyl chloride undergoes nucleophilic substitution much more easily than chlorobenzene. Explain.

Liquids can be far more easily compressed than a solid.

Intermolecular forces between two benzene molecules are nearly of same strength as those between two toluene molecules. For a mixture of benzene and toluene, which of the following are not true?

Why interhalogens are more reactive than halogens ?

Why are alkenes more reactive than alkanes ?

a and b are van der Waals' constants for gases. Chlorine is more easily liquefied than ethane because

Equal moles of benzene and toluene are mixed. The vapour pressure of benzene and toluene in pure state are 700 and 600 mm Hg respectively. The mole fraction of benzene in vapour state is :-
