Activity 13.1
Isomerism, naming and drawing structures
Apparatus (for each group of students)
• ballandstick components as follows: 5 carbon atoms (preferably black) 12 hydrogen atoms (preferably white) 12 short single bonds for C–H bonds 5 medium bonds for C–C bonds 2 longer bonds for forming one C=C bond
• three overhead transparency sheets plus appropriate pen • access to an overhead projector
Procedure
You are given three assignments. For each one, allow approximately 10 minutes.
1 a Construct models representing all the alkanes with the formula C5H12. [3] b Write/draw the structural and skeletal formulae for each compound.
Record your results on an overhead transparency sheet. [6]
2 a Construct models representing all the alkenes with the formula C5H10. [6] b Write/draw the structural and skeletal formulae for each compound.
Record your results on an overhead transparency sheet. [12]
3 a Construct models representing all the compounds with the formula C5H10 that have a cyclic component. [5]
b Draw the skeletal formula for each compound. Record your results on an overhead transparency sheet. [5]
