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.
(a) Using the electronegativities of Br and Cl, estimate the
partial charges on the atoms in the Br¬Cl molecule. (b) Using
these partial charges and the atomic radii given in Figure
7.8, estimate the dipole moment of the molecule. (c) The
measured dipole moment of BrCl is 0.57 D. If you assume the
bond length in BrCl is the sum of the atomic radii, what are
the partial charges on the atoms in BrCl using the experimental
dipole moment?
