VSEPR valence-shell electron-pair repulsion (abbreviated VSEPR and pronounced VES- per ) theory basic principle is valence electrons around a central atom stay as far apart as possible to minimize the repulsions
Polarity Polarity is the uneven partial charge distribution between various atoms in a compound. Atoms, such as nitrogen, oxygen, and halogens, that are more electronegative have a tendency to have partial negative charges. Atoms, such as carbon and hydrogen, have a tendency to be more neutral or have partial positive charges. Electrons in a polar covalent bond are unequally shared between the two bonded atoms, which results in partial positive and negative charges.
Polarity Polarity Polarity occurs based on the difference in electronegativity between atoms in a molecule having an unequal distribution Electronegativity is an expression of an atom's tendency to attract electrons in a chemical bond In order to determine the polarity of a bond, you must find the difference in the electronegativity of the atoms involved If the difference is between 0.4 and 1.7, the bond will be polar
