IB syllabus for first examinations 2016

11.2 - Hydrocarbons


11.2.1: Draw structural formulas for the isomers of the non-cyclic alkanes up to C6. Structural formulas should indicate clearly the bonding between atoms. For example, for pentane: or CH3CH2CH2CH2CH3 or CH3--(CH2)3--CH3 but not C5H12.





11.2.2: State the names of alkanes up to C6. Name these using IUPAC rules. Consider both straight and branch-chained alkanes.


11.2.3: Explain the relative inertness of alkanes. Refer to bond enthalpies. See 6.4.


11.2.4: Draw structural formulas and state the names for straight-chain alkenes (CnH2n, where n is between 2 and 5). Geometric (cis­trans) isomers are not required.


11.2.5: Describe complete and incomplete combustion of hydrocarbons. The formation of CO and C during incomplete combustion should be related to environmental impacts and oxidation­reduction.



11.2.6: State that the combustion of hydrocarbons is an exothermic process. See 6.3 and 6.4
