The objective of this module is to introduce hydrocarbon structure, including analysis of the bonding environments for carbon.
Page 1Introduction - ReviewIntroduction to hydrocarbon structure both in chains and rings with an emphasis on each carbon being involved in four bonds
5 marksPage 2QuestionsFour pages where users enter the number of hydrogens at the carbons in various branched and unbranched hydrocarbon structures with a view to generating the condensed structure for the hydrocarbon. Users are also asked to idenify carbons in similar bonding environments preliminary to introducing constitutional isomerism
1 marksPage 7IsomersSeven pages in which users are asked to identify structures representing compounds that are constitutional isomers of one another and to, for specified carbon chain lengths, deduce from the symmetry of the chain the number of mono methyl isomers for given hydrocarbon chain lengths
3 marksPage 13QuestionPractice identifying methyl groups are in equivalent bonding environments
Page 14Carbon skeletons - ReviewIntroduces a systematic approach to deducing the number of constitutional isomers for a hydrocarbon with a specified number of carbons. This involves an analyses using increasingly shorter chain lengths with more methyl branches
3 marksPage 16QuestionsThree question pages where users deduce the number of possible constitutional isomers for C5 and C6 alkanes and then show that the analysis using only methyl branches revealed all possible isomers for C6 alkanes
