21I think in (I) there is resonance but in (II) is not.

71Yes. In the second compound the resonance effect is not extended and hence the lone pair of electrons are freely available.
7I think in the 1st compound the lone pair of N can easily resonate with the benzene ring. So it is a stronger acid or on the other hand it is a weaker base.(as the conjugate baase is stabilised due to resonance).
1we can also see the electron density on N due to ch2 group and phenyl group
