Which one of the following bonds will be the strongest
1. Bond between a nitrogen atom and a hydrogen atom
2. Bind between a nitrogen atom and a nitrogen atom
Give a reason for the answer
The bond between a nitrogen atom and a nitrogen atom will be the strongest.
The reason for this is that nitrogen atoms are capable of forming triple bonds with each other, resulting in a very strong bond. Triple bonds involve the sharing of three pairs of electrons between the atoms, which provides a high degree of electron density and a strong attraction between the nuclei of the nitrogen atoms.
On the other hand, the bond between a nitrogen atom and a hydrogen atom typically involves the sharing of only one pair of electrons. This results in a weaker bond compared to the triple bond between nitrogen atoms.
Therefore, the bond between a nitrogen atom and a nitrogen atom is stronger than the bond between a nitrogen atom and a hydrogen atom.
The bond between a nitrogen atom and a nitrogen atom is stronger compared to the bond between a nitrogen atom and a hydrogen atom. The reason for this is that both nitrogen atoms in a nitrogen-nitrogen bond have the same electronegativity, meaning they attract electrons equally. This results in a more stable bond due to the shared electron density being distributed evenly between both nitrogen atoms.
On the other hand, in a nitrogen-hydrogen bond, the nitrogen atom is more electronegative than the hydrogen atom. This causes the nitrogen atom to pull the shared electrons closer to itself, creating a partial negative charge on the nitrogen atom and a partial positive charge on the hydrogen atom. This polarity weakens the bond between nitrogen and hydrogen compared to the bond between two nitrogen atoms, making it less strong.
