Alkanes. For each question there are four possible answers, A, B, C, and D. Choose the one you consider to be correct. 1 Four students, W, X, Y and Z, made the following statements about alkanes and alkenes. W ‘Bromine reacts with alkanes by electrophilic substitution.’.
The first four members of the alkanes are methane, ethane, propane and butane. Alkane molecules can be represented in the following forms: (C₂H₆ or drawn out version). Students should be able to recognise substances as alkanes given their formulae in these forms.
Discuss the complete and incomplete combustion of these alkanes and the trend in the energy changes they produced. You should give word equations in your answer.
