SOLUTION (a) The Lewis structure of the SnCl3 ion looks like this: the central atom of Sn is surrounded by a pair of unbound electrons and three single bonds. Therefore, the geometry of the electron pairs is tetrahedral, with three of the angles occupied by the bonding electron pairs.

As we can see, the molecular geometry of XeF4 has the symmetrical distribution of the electrons and they form a single square plane formation. We can therefore say that XeF4 is non-polar.
CCl4 is an example of a non-polar molecule. The four bonds of carbon tetrachloride (CCl4) are polar, but the molecule is not polar because the polarity of the bond is interrupted by the symmetrical tetrahedral shape. When other atoms replace some of the Cl atoms, the symmetry is broken and the molecule becomes polar.
The chemical compound phosphorus pentachloride with the chemical formula PC15 is a non-polar molecule. The molecular geometry of phosphorus pentachloride is symmetrical, which neutralizes the molecule’s binding dipoles to make it non-polar.
The number of lone pairs of electrons in this molecule is 3 and the number of atoms with valence electrons is 2. So 3 + 2 = 5 also determines sp3d hybridization. The shape of the I3 molecule is linear. There are three iodine atoms, one of which is also negatively charged.
Let’s do the Lewis structure for SiH4. In the periodic table silicon, group 4, 4 valence electrons hydrogen, group 1, 1 valence electron, but we have four. So 4 plus 4: 8 electrons of the total valence. Put Yes in the middle, hydrogen always comes out.
The molecular geometry of BrF5 is square pyramidal with asymmetric charge distribution on the central atom.
In chemistry, perbromination is the anion with the chemical formula BrO− 4. It is an oxyanion of bromine, the conjugate base of perbromic acid, with bromine in the oxidation state +7.

The bromine anion BrO-3 is a bromine-based oxanion. A bromate is a chemical compound that contains this ion.
Based on VSEPR theory: the molecular form of PCl3 is trigonal pyramidal and the electron geometry is tetrahedral. The central phosphorus atom is sp3 hybrid and has three bond pairs and a single electron pair.
Hybridization of BrF5 (bromine pentafluoride)
In sp hybridization, an s orbital and a p orbital hybridize to form two sp orbitals, each consisting of 50% s and 50% p characters. This type of hybridization is necessary when an atom is surrounded by two groups of electrons.
There are 32 valence electrons in the perbromate.
