A subadditive function is a function, having a domain A and an ordered codomain B that are both closed under addition, with the following property: An example is the square root function, having the non-negative real numbers as domain and codomain, since we have:
Sbf5 is a nonpolar bond because the dipole moment is nonexistent. If you were to draw the chemical structure you would see that due to electronegativity of the fluorine atoms, that the vectors where the electrons are pulled away from the SB cancel one another, forcing SbF5 to be a nonpolar covalent molecule. non-polar compound occurs when there is an equal sharing of electrons between two different atoms. Examples of household non-polar compounds include fats, oil and petrol/gasoline.
SiCl4 is covalent compound. Si--Cl bond is polar because Cl is more electronegativity than Si. Structure of SiCl4 molecule is tetrahedral. THis structure is symmetry which brings to the non-polar characteristic of SiCl4 molecule. This is because all the dipole moment in Si--Cl bond cancel out each other.The bond between Si--Cl is covalent bond. SiCl4 molecules hold together by intermolecular Van der Waals force of attraction.tructure of SiCl4 molecule is tetrahedral. THis structure is symmetry which brings to the non-polar characteristic of SiCl4 molecule. This is because all the dipole moment in Si--Cl bond cancel out each other.
