Question

any hydrocarbon compound in which a ring has bonding similar to benzene

Answer 1

Answer:

Explanation:

Nitrobenzene is also an aromatic compound. The delocalizable* electrons in nitrobenzene are only the ones present inside the benzene structure, hence the pi bonds in the group NO2 is ignored and Huckels rule is followed similar to that of Benzene structure itself.

Answer 2

Explanation:

Benzene is the archetypical aromatic compound. It is planar, bond angles=120º, all carbon atoms in the ring are sp2 hybridized, and the pi-orbitals are occupied by 6 electrons. The aromatic heterocycle pyridine is similar to benzene, and is often used as a weak base for scavenging protons. Furan and pyrrole have heterocyclic five-membered rings, in which the heteroatom has at least one pair of non-bonding valence shell electrons. By hybridizing this heteroatom to a sp2 state, a p-orbital occupied by a pair of
