Since we only answer up to 3 sub-parts, we’ll answer the first3. Please resubmit the question and specify the other subparts (up to 3) you’d like answeredTo predict the structures of any compound , draw the Lewis dot structure first. The Lewis electron dot structure is made by considering the valency of the elements involved. It gives an idea about the no. of bond pairs, lone pairs and non bonding electrons. So, to predict the structure of H3O+ Draw the Lewis dot structure- O- Atomic number=8 , Valency = 2 H- Atomic number=1 , Valency =1 Now, notice that oxygen makes 3 bond pairs with H and has 1 lone pair. So for 4 pair of electrons, structure should have been tetrahedral but since there is a lone pair, so the structure becomes Trigonal PyramidalTo predict the structure of PCl4- Draw the Lewis dot structure- P- Atomic number=15 , Valency =3 Cl-Atomic number=17 , Valency =1 P forms 4 bond pairs with Cl and has one lone pair. The four Cl atom normally give it a tetrahedral shape. But, the presence of a lone pair over the P distorts this geometry and instead gives it a SEE-SAW Geometry. To predict the structure of SnCl3- Draw the Lewis dot structure- Sn- Atomic number=50 , Valency =4 Cl-Atomic number=17 , Valency =1 The 3 Cl atoms surround the Sn atom forming three bond pairs. There lies one lone pair. Had all been bonding pair, the structure would have been tetrahedral. But as there is one lone pair, the molecular geometry is TRIGONAL PYRAMIDAL
