Molecular because it is between 2 non-metals.
SiF4 is molecular.
Sulfur is a ionic compound
It's Ionic
SiF4 is a polar covalent compound
Tetrahedral
No, it is a covalent molecule.
:Structure of SiF4 is a regular tetrahedron, any regular geometry has net zero dipole moment as all individual dipole in a molecule cancel the effect of each other. About paramagnetic behaviour of oxygen gas, according to the Molecular Orbital theory oxygen has two unpaired electron in its Pi anti bonding molecular orbital, which is the cause of their paramagnetism.
SiF4 is a covalent molecule. The rule that a bond is ionic if the difference in electronegativities is >1.7 is only a rule-of-thumb. It has a low melting point etc. and all the characteristics of a covalent molecular substance. The covalent bonds however are very polarised and SiF4 is rapidly hydrolysed by water.
I believe you are asking for the molecular structure - the tetrahedral.
Is BO ionic or a molecular
CO is molecular
Silicon Tetrafluoride has a tetrahedral molecular geometry. That means there are 4 F atoms around the central atom Si.
Iron(III) bromide is an ionic compound.
It is ionic because chromium is a metal.
HCIO4 is an ionic compound.
