Nonane (C9H20\text{C}_9\text{H}_{20}C9H20) is a liquid hydrocarbon commonly found in kerosene-based aviation fuels.
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} C9H20+→+As the chain length of a hydrocarbon molecule increases, its boiling point increases. Explain this trend in terms of intermolecular forces.
A chemical technician wants to distinguish a sample of nonane (C9H20\text{C}_9\text{H}_{20}C9H20) from nonene (C9H18\text{C}_9\text{H}_{18}C9H18). Describe a chemical test and the expected observation for each compound to help the technician identify them.
