Question

Which covalent bond is the strongest?

Answer 1

1. Covalent bonds are formed by the direct sharing of electrons.
2. The number of electrons bonded will depend on the outer shell electrons of an atom.
3. The valence shell electrons of one atom combine with the mutual sharing of other atoms and thereby forming covalent bonds.
4. Covalent bonds are generally formed between nonmetallic elements such as hydrogen and oxygen, elements.
5. Covalent bonds are of three types- single, double, and triple bonds.
6. Among all sigma bonds $\mathrm{\delta }$ are the strongest covalent bonds as they are simply formed by direct (head on) overlapping atomic orbitals.
7. Single bonds are formed by two atoms in which one electron from each atom makes a single covalent bond also known as a sigma bond.
8. The double and three bonds contain $\mathrm{\pi }$ bond that is formed by sideways overlapping of atomic orbitals and thus it is weaker than the $\mathrm{\delta }$ sigma bond.
9. They are denser and most stable in nature.
10. This can be represented as$\left(-\right)$.
11. Example: Hydrogen Chloride.
12. Thus, the strongest covalent bond is the (sigma bond).
