What is Covalent Bond?
admin 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…
What do you mean by Pi (π) Bonds? How it is formed?
Pi (π) Bonds When sideways overlapping or lateral overlapping of the two atoms take place is known as lateral overlap of their ‘p’ orbital, and the bond formed is known…
Explain the concept of resonance Energy and give rules to write resonating structure
Resonance Energy The difference between the actual energy of the molecule and that of most stable resonating structure is known as Resonance Energy. Let us suppose that a molecule have…
Construct the wave Function for the sp3 hybrid orbitals
The four sp3 hybrid orbitals are as follows: Ψ 1 = a 1 ф s + b 1 ф py +d 1 ф pz Ψ 2 = a 2 фs…
What is the formula for calculating the bond order?
Bond order is given by Bond order = /2 Bond order is directly proportional to bond dissociation energy and inversely proportional to bond length i.e. higher the bond order, larger…
What do you mean by HOMO and LUMO?
HOMO : The highest occupied molecular orbital LOMO : Lowest unoccupied molecular orbital. The term Band gap means the difference between energies of the HOMO and LUMO. It will also…
