Nonane (C9H20\text{C}_9\text{H}_{20}C9​H20​) is a liquid hydrocarbon commonly found in kerosene-based aviation fuels.

a.

Complete and balance the chemical equation for the complete combustion of nonane:

C9H20+‾→‾+‾\text{C}_9\text{H}_{20} + \underline{\qquad\qquad} \rightarrow \underline{\qquad\qquad} + \underline{\qquad\qquad}C9​H20​+​→​+​

b.

As the chain length of a hydrocarbon molecule increases, its boiling point increases. Explain this trend in terms of intermolecular forces.

c.

A chemical technician wants to distinguish a sample of nonane (C9H20\text{C}_9\text{H}_{20}C9​H20​) from nonene (C9H18\text{C}_9\text{H}_{18}C9​H18​). Describe a chemical test and the expected observation for each compound to help the technician identify them.
