Types of Chemical Bonds

Ionic Bonding↪ Ionic bonding is a type of chemical bonding which involves a transfer of electrons from one atom or molecule to another. ↪ Here, an atom loses an electron which is in turn gained by ...

Valence shell electron pair repulsion (VSEPR) theory:

↪ Valence Shell Electron Pair Repulsion (VSEPR) theory is a simple theory to predict and explain the shape and bond angles in a number of simple covalent molecules and ions. ↪ This theory was propo...

Hydrogen Bonding

↪ The attractive force between a hydrogen atom and strong electronegative atom (Such as N, F and O) of same or different molecules is called hydrogen bond. ↪ It is denoted by dotted lines. Types o...

Concept of Sigma and Pi bond

Sigma Bond (σ) ↪ When the overlap of orbital’s of two atoms takes place along the line joining the two nuclei (orbital axis) then the covalent bond formed is called sigma (σ) bond. ↪ These bonds ca...

Resonance in Chemical Bonding

↪ There are molecules and ions for which drawing a single Lewis structure is not possible. For example, we can write two structures of O3.↪ In (A) the oxygen-oxygen bond on the left is a double bon...

Valence Bond Theory(VBT) and its postulates

Heitler and London introduced Valence Bond Theory. This is primarily based on the concepts of atomic orbitals, electronic configuration of elements, overlapping of atomic orbitals and hybridization...

Polar Covalent Bonds

↪ This type of covalent bond exists where the unequal sharing of electrons occurs due to the difference in the electronegativity of combining atoms. ↪ More electronegative atom will have a stronger...
