ecide whether each molecule or polyatomic ion is polar or nonpolar. f the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. For example, if the molecule were HCl and you decided the hydrogen atom was closest to the negative side of the molecule, you'd enter "H" in the last column of the table. polar or nonpolar? atom closest to negative side molecule or polyatomic ion O polar O nonpolar NOCI polar NH3 nonpolar polar Br2 nonpolar
Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.
Polar molecule:
These are molecules in which there is an electronegativity difference between the bonded atoms. In polar molecules,
one end is positive while the other end is slightly negative.
Non-polar molecule:
These are the molecules when electrons are shared between atoms of a diatomic molecule. There is no separation of charge. Hence no positive and negative poles are formed.
