Question 1 Report
Benzene contains six carbon atoms and six hydrogen atoms.
(a)(i) Draw two stable structures of benzene to show how these atoms are arranged.
(ii) What is the concept behind these structures?
(b) Give (i) two uses of benzene. (ii) one industrial source of benzene.
Answer Details
(a)(i) Kekulé structures of benzene, C6H6
(a)(ii) The two structures illustrate resonance. The actual benzene molecule is a resonance hybrid in which the c0-electrons are delocalized over all six carbon atoms. Thus, all the carbon-carbon bonds are identical and are intermediate between a single and a double bond.
(b)(i) Uses of benzene
- It is used in the manufacture of chemicals such as disinfectants.
- It is used in the manufacture of perfumes.
(b)(ii) Industrial source of benzene
Benzene is obtained from coal tar, produced during the destructive distillation of coal.
