Q56E
Question
Write the two resonance structures for the pyridinium ion, \({C_5}{H_5}N{H^ + }. \)
Step-by-Step Solution
Verified Answer
1Step 1: To find the pyridine or pyridinium ion:
The given ion is pyridinium ion.
Pyridine is derivative of benzene which contains one nitrogen atom in the ring instead of one carbon atom.
This structure is also aromatic like benzene since a lone pair of nitrogen isn't included in the \(\pi \) conjugated system inside the ring.
The resonance forms of pyridinium ion:
Resonance forms of the pyridinium ion
2Step 2: The resonance structures of pyridinium ion
All \(\pi \)bonds inside the ring move to the adjacent single C-C bond, which becomes a double bond.
On the other hand, double bonds become single as \(\pi \)electrons move.
