Questions
Write the molecular formula and structure of cyclohexane. How many covalent bonds are there in a molecule of cyclohexane?
Draw the structure of the molecule of cyclohexane (C6H12)·
Solution
The molecular formula of cyclohexane is C6H12.
Its structure is as follows:
A cyclohexane molecule has six carbon-carbon single bonds and twelve carbon-hydrogen single bonds. Therefore, there are 18 covalent bonds in one molecule of cyclohexane.
Notes
Students should refer to the answer according to their questions.
