polar molecule and nonpolar molecule

When diatomic molecules are formed from identical atoms, the electrons forming the bonds are shared equally between the atoms e.g.,H 2 , N 2 , O 2 , Cl 2 etc. Such molecules are termed as non-polar as there is no separation of charges. When compounds are formed betw..

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 io..

Methane The shared pair is equidistant from both carbon and hydrogen atoms. Neither the carbon atom, nor the hydrogen atom can pull the shared pair towards itself as there is little difference [carbon = 2.5ev, hydrogen = 2.1ev] in their electronegativiti..

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 symmetrical i.e., centre of the negative charge coi..

Covalent bonds may be non-polar or polar in nature. Non-polar molecule of methane Methane ..

It is smallest particle (of an element or compound), which is capable of independent existence. Molecules are formed by combination of atoms. Molecules are formed by combination of atoms If the molecule is made up of atoms of the same element it is said to be homo-atom..

A soap has two dissimilar ends. At one end is the hydrocarbon chain that is non-polar and hydrophobic (oil soluble). At the other end there is the carboxylate ion that is polar and hydrophilic (water soluble)...

Atoms and Molecules - The smallest particle of an element, which may or may not have independent existence is called an atom, while the smallest particle of a substance which is capable of independent existence is called a molecule. Molecules are classified as homoatom..

The smallest particle of an element, which may or may not have independent existence is called an atom, while the smallest particle of a substance which is capable of independent existence is called a molecule. Molecules are classified as homoatomic and heteroatomic. Homoa..

Molecules of Compounds - A molecule of a compound consists of two or more atoms of different elements joined together in a fixed ratio. Examples: CuSO 4 contains Cu - 1 atom, S - 1 atom, O - 4 atoms A chemical formula represents the composition of a molecule of the sub..
