BON VSEPR Intro Shapes up to 8 NBP 4 - Contents
- 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
- 6 marksPage 3Trigonal bipyramid
- 6 marksPage 4Octahedral
- 8 marksPage 5Shape 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 6TetrahedralQuestions which pertain to the tetrahedral shape and the hash-and-wedge drawing of this orientation of bonds about the central atom
- 13 marksPage 7Shape 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)
- 4 marksPage 8Various geometries
- Page 9Bond angles - ReviewIntroduction to bond angles with a focus on the tetrahedral family of shapes
- 7 marksPage 10QuestionsThese deal with bond angles about trigonal nitrogen, tetrahedral carbon and divalent oxygen in the context of compounds which contain two of these (two pages)
