Question

The maximum number of covalent bonds by which two atoms can be bonded to each other is

• A. four
• B. two
• C. three
• D. none of these

Answer 1

The correct option is C

three

Part 1: The explanation for the correct option

Option C: Three

1. The covalent bond is formed by the mutual sharing of electrons between the atom of the same element or a different element.
2. The type of bond (double/triple) depends on the number of valence shell electrons.
3. The maximum number of valence electrons available for sharing is with $\mathrm{C}\left(4\right)$, but carbon doesn't share $4$electrons with other $\mathrm{C}$ atom and forms ${\mathrm{C}}_2$.
4. Nitrogen$\left(\mathrm{N}\right)$ forms a triple bond with other $\mathrm{N}$ atom and forms ${\mathrm{N}}_2$ molecule.

Part 2: The explanation for the incorrect option

Option A: four

1. There is no possibility of a quadruple bond between two atoms because of the high repulsion between the electrons.

Option B: two

1. There are many compounds with a double bond, but it's not the maximum number of bonds as there is a triple bond also between the atoms.

So, the correct option is C. The maximum number of covalent bonds by which two atoms can be bonded to each other is three.
