Question

How many electrons are contributed by N in pyridine to aromatic sextet? ​

Answer 1

Answer:

the last compound of Imidazole hydrocycle have to nitrogen atoms note that the nitrogen nonbonding electrons pairs for use for the aromatic electron The Other electron pair behave similarly to the electron pair in pyridine

Answer 2

Explanation:

Pyidine's ring atoms, including the nitrogen atom, are all sp2 hybridised. Each ring atom provides one electron to an aromatic system of six electrons in a 2p orbital. One of the five valence electrons on the sp2-hybridized nitrogen atom contributes to the aromatic sextet.
