Page 1Introduction - ReviewIntroduction to VSEPR theory and the shapes of molecules of type AXn where there are no non-bonding electron pairs at the central atom
10 marksPage 2Recognising shapesVarious ball-and-stick models are provided and users identify the number of bonding electron pair regions at the central atom and the shape of the molecule
8 marksPage 3Shape families 1Recognising how the presence of nonbonding electron pairs at the central atom affects the shape for molecules with three electron-pair regions at the central atom
5 marksPage 4TetrahedralQuestions which pertain to the tetrahedral shape and the hash-and-wedge drawing of this orientation of bonds about the central atom
13 marksPage 5Shape families 2Recognising how the presence of nonbonding electron pairs at the central atom affects the shape for molecules with four electron-pair regions at the central atom (two pages)
5 marksPage 9QuestionsThese deal with bond angles about trigonal nitrogen, tetrahedral carbon and divalent oxygen in the context of compounds which contain two of these (two pages)
7 marksPage 10Trigonal bipyramidalTwo pages that introduce the trigonal bipyramid shape and the family of shapes in which there are a total of five electron-pair regions about the central atom
18 marksPage 12OctahedralTwo pages that introduce the octahedral shape and the family of shapes in which there are a total of six electron-pair regions about the central atom
