Which one of the following is not a characteristic of benzene?
- A
Aromaticity
- B
Stability
- C
to follow Huckle rule
- D
High reactivity
The correct answer is High reactivity. Benzene is characterized by its stability and aromatic nature, which make it less reactive compared to many other hydrocarbons. It undergoes electrophilic substitution rather than addition reactions, which is a hallmark of its stability.
In contrast, the other options are true characteristics of benzene: Aromaticity is a defining feature, indicating its unique electron configuration; Stability refers to its resistance to reactions typical of alkenes; and Hückel's rule confirms its aromatic nature based on the count of π-electrons.
Benzene is known for its aromatic nature, which is a fundamental characteristic that defines its structure and stability due to resonance.
Benzene is highly stable compared to many other hydrocarbons, particularly due to its delocalized π-electrons.
The Hückel rule states that a cyclic, planar molecule with (4n + 2) π-electrons is aromatic, which benzene follows, confirming its aromaticity.
Benzene is known for its low reactivity in electrophilic substitution reactions compared to alkenes, making this statement incorrect regarding its characteristics.
