its sp2 hybridisation
In pyridine molecule the Nitrogen atom is involved in Aromatic character of ring if lone pair of nitrogen forms a sigma bond with hydrogen the Aromatic ring (Aromaticity) becomes lass stable so pyridine do not accept the proton easily while Aromaticity is not involved in pi-pyridine so its nitrogen atom easily donates the electron pair to a proton .

Bases containing the pyridine substructure, or derived from pyridine as a starting material. Pyridine is basically benzene with one of the carbons substituted with a nitrogen, if that helps.
Pyrrol is a weak acid as the pair of electrons found on the nitrogen atom are delocalised into the five membered ring thus making the electrons unavailable for donation. In addition, the hydrogen that is bonded with the nitrogen atom can be removed without causing disruption to the aromatic sextet. Pyridine is basic as the lone pair on nitrogen is not involved in the delocalised system and thus can be donated.
sp3 is the hybridization of the nitrogen atom in NCl3.
The nitrogen atom undergoes sp3 hybridization in ammonia.

Pyridine itself (unsubstituted) is basic due to presence of lone pare of electron on nitrogen atom which is not involved in aromatic character , methyl at 4th (Para) position is electron donor due to hyper-conjugation so electrons density at nitrogen becomes increase so 4-methyl pyridine is more basic as compare to unsubstituted pyridine.

The pyridine molecule is a planar and cyclic shape, similar to a regular hexagon. It has a nitrogen atom in the center and five carbon atoms connected to it, forming a ring.

Sp2,120 is the hybridization of the central atom in SO2.
Niacin does not contain nitrates. It is a carboxylic acid, and not a nitrate. It does, however, contain a nitrogen atom because it contains a pyridine ring.
