Explanation:

* Nitrogen gas (N2) has a triple bond between the two nitrogen atoms. Triple bonds are very strong and require a large amount of energy to break. This is due to the presence of three shared electron pairs between the nitrogen atoms.

* Hydrazine (N2H4) has a single bond between the two nitrogen atoms and single bonds between the nitrogen and hydrogen atoms. Single bonds are weaker than triple bonds.

Bond strength is inversely proportional to bond length. The nitrogen-nitrogen triple bond in N2 is shorter than the nitrogen-nitrogen single bond in N2H4. This shorter bond length indicates a stronger bond.

Therefore, the triple bond in nitrogen gas (N2) makes it have a much stronger bond than the single bond in hydrazine (N2H4).
