Explain what is meant by the term isomers.
The displayed formula of hexane (C6H14\text{C}_6\text{H}_{14}C6H14) is:
Which one of the displayed formulae below does not represent an isomer of hexane?
Choose from A, B, C, or D.
Hexane belongs to a homologous series of compounds called alkanes. The general formula of the alkanes is CnH2n+2\text{C}_n\text{H}_{2n+2}CnH2n+2.
Hexene belongs to a homologous series of compounds called alkenes. Give the general formula of the alkenes.
Complete the following structural formula of hexene (C6H12\text{C}_6\text{H}_{12}C6H12) by describing where the covalent carbon-to-carbon single and double bonds must be inserted.
When hexene is added to bromine water, and the mixture is shaken, a reaction occurs. State the type of reaction and give the colour of the bromine water before and after the reaction with hexene.
Explain, in terms of the bonds present, why hexane is described as saturated and hexene as unsaturated.
