Given statements about Tropolone:
Statement-I: Tropolone is aromatic and has 8π electrons. Statement-II: π electrons of >C=O group in tropolone is involved in aromaticity.
Choose the correct option:
- a
Both true
- b✓
Statement-I true but Statement-II false
- c
Statement-I false but Statement-II true
- d
Both false
Statement-I true but Statement-II false
Tropolone has a total of 8 π electrons, but only 6 π electrons within the ring are involved in aromaticity. The first statement is correct that it has aromatic character and 8 π electrons.
Second statement is incorrect because the pi electrons of the carbonyl group are not involved in aromaticity.
