Question
Aromatic hydrocarbons are also called _____________
a. alkane
b. alkynes
c. alkenes
d. arenes
Solution
Aromatic hydrocarbons are also called d. arenes.
Explanation
Aromatic hydrocarbons are a class of hydrocarbons that contain one or more aromatic rings. Aromatic compounds are characterized by their stability due to resonance, which allows electrons to be delocalized across the ring structure. The most common example of an aromatic hydrocarbon is benzene, which consists of six carbon atoms connected in a ring with alternating double bonds. The term "arene" specifically refers to these cyclic compounds with a certain degree of unsaturation and aromaticity, distinguishing them from alkanes (which are saturated hydrocarbons), alkenes, and alkynes (which are unsaturated hydrocarbons with double and triple bonds, respectively). Hence, the correct answer is d. arenes.
