A water molecule is angular despite the fact that it has 4 electron pairs around oxygen. Two of the pairs are lone pairs and are “invisible”. Shapes of molecules. 1.
The valence-shell electron-pair repulsion (VSEPR) model provides a simple method for predicting the shapes of such species. • The Cambridge Structural
For example; four electron pairs are distributed in a tetrahedral shape. If there is one lone pair of electrons and three bond pairs the resulting molecular geometry is trigonal pyramidal (e.g. NH3). If there are two bond pairs and two lone pairs of electrons the molecular geometry is angular or bent (e.g. H2O).
The shape of simple covalent molecules is determined by the number of bonding There are five basic shapes and then variations on each shape where lone

Bond angles the bond angles are “squashed” slightly compared to the basic structure without lone.Lewis structures are very useful in explaining the bonding in simple molecules and in predicting molecular shapes. • They do not explain why electrons in bond.
Quite remarkably, the shapes of most ABn molecules can be derived from just five basic geometric arrangements, shown in ? Figure 9.3. All of these are highly.
To be able to use VSEPR theory to predict shapes, the molecule first needs These are quite simple: treat multiple bonds as single bonds, and the AXE system
