polarity of bonds

The bond between two unlike atoms, which differ in their affinities for electrons is said to be a polar covalent bond. When a covalent bond is formed between two atoms of different elements, the bonding pair of electrons will lie more towards the a..

When the atoms forming bonds are different, the electron attracting powers of the two atoms in a bond may differ. Then, the shared pair will be displaced towards the atom having more electronegativity. For example, in a moleclule of HCl, the electronegativities of Cl and H are ..

Non-polar covalent bond When a covalent bond is formed between two atoms of the same element, the shared electron pair will lie exactly midway between the two atoms i.e. the electrons are equally shared by the atoms. The resulting molecule will be electrically symm..

Two types of covalent bonds are formed depending upon the electronegativity of the combining elemen..

The sp 2 hybridized carbon atom in the C-X bond in haloarene molecule is more electronegative than the sp 3 hybrid carbon atom in alkyl halide. This carbon has less tendency to release electrons to the chlorine atom and so the C-Cl bond in aryl halides is less polar..

Polar Molecules When compounds are formed from elements whose atoms have different electronegativities, the electrons forming the bonds will have a tendency to be attracted closer to the more electronegative element. In such instances covalent molecules develop some ionic charac..
