Which of the following statements is/are true of benzene?
1. Benzene belongs to a class of cyclic unsaturated hydrocarbons known as the aromatic hydrocarbons.
2. Benzene undergoes substitution reaction in which hydrogen atoms are replaced by other atoms.
3. sp² hybrid orbitals on each carbon of a benzene molecule are used to form the H-H and H-C σ bonds.

Question

Quizplus · Accepted Answer

1. Benzene is indeed an aromatic hydrocarbon, characterized by a ring structure with alternating double bonds that follow Huckel's rule. 2. Benzene typically undergoes substitution reactions rather than addition reactions, preserving its aromatic structure. The statement about sp² hybrid orbitals is incorrect; benzene's carbon atoms use sp2 hybrid orbitals for forming σ bonds.
