Its D. stannic fluoride, SnF4
SnF4
SnF4
The chemical formula of stannous fluoride is SnF2. The structural formula of stannous fluoride shows the arrangement of atoms, with an Sn atom in the center surrounded by two F atoms. It can be represented as Sn-F-F.
SnF4 is ionic because it consists of a metal cation (Sn4+) and a nonmetal anion (F-), forming an ionic bond.
First we have to start by determining what charge does Sn have to form this compound. Remember that Fluorine has -1 charge (F-1) and there are 4 of them. That means that Sn must have a +4 charge; therefore, the compound would be called: Tin(IV) fluoride or Stannic fluoride.
well BrF3 will auto dissociate to give BrF4- + BrF2+ ...the KF will give a F- to the BrF3 obviously this giving is really due the higher electronegativity of the fluorine thus their will be an increase in the amounts of BrF4- in solution .Using the solvent-system definition of an acid or base.Any specie (molecule ,ion)which increases the anionic or negatively charged amounts of species in solution is a base.So KF definitely behaves as a base. You can use this same reasoning for SnF4 and try and figure that one out on your own.good luck .
SnF4 is a polar covalent compound. Although it consists of a metal and a non-metal, the electronegativity difference between Sn (metal) and F (non-metal) is not large enough to form an ionic bond. Instead, the sharing of electrons between Sn and F results in a polar covalent bond.
