Page 2VSEPR Intro - ReviewDescription of how the shape of a molecule depends on the number of electron pair domains for molecules with two, three or four bonding pair domains
Page 3Lewis structure - ReviewDescription of how to draw Lewis structures for a compound of type EXn from the composition of the molecule. This description is limited to atoms that form single bonds with the central atom (hydrogen and halogen).
8 marksPage 4QuestionsTwo examples (CH2Cl2 and BCl3) which involve first drawing the Lewis structure and deducing the shape from the Lewis structure
Page 6Non-bonding pairs - ReviewDescribes how the presence of non-bonding electron does not affect the orientation of the electron pairs about the central atom but does affect the description of the shape of the molecule
9 marksPage 7Questions aTwo examples (OCl2) and PCl3) which involve first drawing Lewis structures and then deducing the shape of the molecule from these
10 marksPage 8Questions bFour questions in which users deduce the arrangement of electron pair domains about the central atom from the composition of the molecule and the given number of non-bonding electron pairs at the central atom
1 marksPage 9Bond anglesDescription of the expected bond angles associated with particular shapes
1 marksPage 10QuestionsDeduction of the shape and bond angle from given molecular formulae and numbers of non-bonding electron pairs at the central atom
