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.
BF3, XeF4 Symmetric ball shaped molecules such as tetrahedral and octahedral eg CF4 and SF6 The above apply in case of symmetrical substitution about the central atom eg CF4 is non polar but CH3F and CH2F2 and CHF3 are polar.xpect polar molecules in: V shaped (angular) molecules eg CF2 T shaped molecules eg ClF3 See-saw molecules eg SF4 Pyramidal molecules such as trigonal pyramidal or square pyramidal eg NF3, BrF5 Note: ClF3 and SF4 has to move in the polar molecules.
