In Pyrrole, lone pair on N is delocalised in the ring.
This is because without the lone pair, there are only 4 pi electrons in ring and this is not aromatic. When lone pair on N is delocalised, ring would have 6 pi electrons and hence it is aromatic. So, no lone pair is readily available that can act as base.
In puridine, the ring already has 6 pi electrons in ring and hence t is aromatic.
So, lone pair on N is localised and can be donated easily.
So, puridine is stronger base.
Answer: puridine

Nuclear magnetic resonance (NMR)
spectroscopy can be used to gather information about the structure
of a compound. The chemical shift of peaks in a 1H NMR or a 13C NMR
spectrum can be used to gather information about the types of
neighboring functional groups. The spin-spin splitting pattern in a
1H NMR spectrum can be used to determine the number of hydrogen
atoms on neighboring carbon atoms.

Nuclear magnetic resonance (NMR) spectroscopy is a powerful method, in which transitions occur between different angular momentum states of an atomic nucleus. Let us consider the case of 23Na, a biologically important element, for which the angular momentum quantum number is S = 3/2. (a) Calculate the magnitude ISI of the angular momentum of the 23Na nucleus in SI units: (b) Sketch a diagram of the possible orientations of the angular momentum relative to an arbitrary axis and label them...
