Incorrect statement regarding aromaticity is-
1. Compound should have a planar structure.
2. The π–electrons of the compound are completely delocalized in the ring.
3. The total number of π–electrons present in the ring should be equal to (4n + 2) , where n = 0, 1, 2 … etc. This is known as Huckel’s rule.
4. Compound should have a linear structure
Not an aromatic molecule is/are -
4. All of the above
Incorrect statement towards reactivity of benzene is
1. It undergoes electrophilic substitution reactions very easily
2. Nucleophiles are attracted by a benzene ring
3. Benzene is a planar molecule
4. It has 12 sigma bonds
Benzene is extraordinarily stable, though it contains three double bonds, because of -
1. Delocalized protons
2. Delocalized neutrons
4. None of these
The numbers of structural isomers of (one double bond) and (one triple bond) are -
