Question

Bonds present in Nitrogen molecule are

• A. 3σ
• B. 1σ and 2π
• C. 3π
• D. 2π and 2σ

Answer 1

The Correct Option is B

The nitrogen molecule (N₂) is a diatomic molecule consisting of two nitrogen atoms. To understand the bonding, consider the electronic configuration of a nitrogen atom, which is 1s² 2s² 2p³. Each nitrogen has five valence electrons.

When two nitrogen atoms form a molecule, they share three pairs of electrons to complete their octets, forming a triple bond. This triple bond comprises:

• One sigma (σ) bond: This bond is formed by the head-on overlap of two sp orbitals (or in some texts, p-orbitals) from each nitrogen atom.
• Two pi (π) bonds: These bonds are formed by the side-by-side overlap of the remaining unhybridized p orbitals from each nitrogen atom.

Therefore, the correct type of bonds in a nitrogen molecule is one sigma (σ) bond and two pi (π) bonds.

In conclusion, the bonds present in a nitrogen molecule are categorized as 1σ and 2π.

Answer 2

Explanation:
A nitrogen molecule (\(N_2\)) consists of two nitrogen atoms bonded by a triple bond. This triple bond includes:

• 1 sigma (σ) bond
• 2 pi (π) bonds

So, the bonding in \(N_2\) is:
\(N \equiv N\) → one σ and two π bonds.

Hence, the correct answer is: 1σ and 2π.
