What is role of photochemistry in everyday life? Discuss the damaging effects of photochemistry.
Photochemistry plays an important role in everyday life. Some of the examples are given below: 1. In vision 2. In photosynthesis 3. In the manufacture of many inorganic compounds. For…
What do you mean by Chemical Bonding?
A chemical bonding is an attraction between atoms or molecules and allows the formation of chemical compounds, which contain two or more atoms. It is caused due to redistribution of…
What is Ionic Bond?
In this type of bond, the outer atomic shell of one atom has a vacancy which allows addition of one or more electrons. These newly added electrons potentially occupy a…
What are theactors influencing the Formation of Ionic Bond?
The factors which influence the formation of an ionic bond between a metal and non-metal are discussed below: 1. Ionization Energy: The amount of energy required to remove (to infinity)…
What is Covalent Bond?
A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, and other covalent bonds. In short, the attraction-to-repulsion stability…
What are the types of Covalent Bond?
Two types of covalent bonds are formed depending upon the electro negativity of the combining elements. 1. Non-polar covalent bond 2. Polar covalent bond Non-polar covalent bond During the Formation…
What are the characteristic properties of covalent compounds?
The main characteristic properties of covalent compounds are: 1. The covalent compounds do not exist as ions but exist as molecules because of weak inter molecular force. 2. The covalent…
Compare Valence Bond Theory (VBT) and Molecular Orbital Theory (MOT)
SIMILARITIES: Valence Bond Theory (VBT) and Molecular Orbital Theory (MOT) have the following common features: 1. The Basic principle is same in both the theories. Both involve distribution of electrons.…
Explain how the single covalent bond is formed with example.
Single covalent bond Formation of a covalent bond by sharing of one pair of electrons i.e. two electrons are involved is called a ‘single covalent bond’, or simply a single…
