Which of the following is true about arenes?:
Correct answer: A. It has low melting and low boiling points
- A. It has low melting and low boiling points
- B. It has high melting and high boiling points
- C. It has low melting and high boiling points
- D. It has a high solubility in polar solvents
Explanation
Arenes are aromatic compounds (contain benzene rings). Hence, they only possess weak Vander Waal's forces as their intermolecular forces of attraction. Hence, they would have a low melting and boiling point and they wont dissolve in polar solvents such as water.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
