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.
Please answer question 17 part A and B
![By convention, the lattice energy is the energy
required to form one mole of a solid ionic crystalline
lattice from its gaseous ions. Since we cannot
directly measure lattice energies, we generally use
the Born-Haber cycle to calculate the lattice energy

from other measurable quantities. For instance, the
Born-Haber cycle of sodium chloride is shown
below.
Rank the following ionic compounds by the magnitude of their lattice energy.
(Figure 1)
Rank from highest to lowest magnitude of lattice energy.
In this cycle, the lattice energy is calculated using
the following parameters. The associated reaction
for each is shown in Figure 1.
