Isomerism: structural and E/ZEdexcel A-Level Chemistry: Mind map

Exam questions on Isomerism: structural and E/Z

1. A chemist is cataloguing the isomers of the alkane C₅H₁₂ and of the haloalkane C₄H₉Br.
   Give the IUPAC names of the two branched isomers of C₅H₁₂.2 marks
2. A student is studying alkenes with the molecular formulae C₄H₈ and C₅H₁₀, and how the arrangement of groups around the carbon-carbon double bond affects their properties.
   Explain what causes E/Z isomerism and state the condition on the groups attached to the C=C bond for a molecule to show it.2 marks
3. Alkenes with the molecular formula C₅H₁₀ are used as models to study isomerism. Ignore cyclic compounds in this question.
   Give the structural formula and name of each unbranched alkene with molecular formula C₅H₁₀. State which one shows E/Z isomerism, with a reason.3 marks
