Answer:

Nitrogen to nitrogen bond in [tex]N_{2}[/tex] higher in strength than nitrogen to nitrogen bond in [tex]N_{2}H_{4}[/tex]

Explanation:

Lewis dot structure of [tex]N_{2}[/tex] reveals that there exist a triple bond between two N atoms.
Lewis dot structure of [tex]N_{2}H_{4}[/tex] reveals that there exist one single bond between two N atoms.
For covalent bond between two given atoms, force constant of a triple bond is almost 3 times higher than force constant of a single bond.
As bond energy is proportional to force constant of a bond therefore strength of triple bond is higher than strength of single bond.
So nitrogen to nitrogen bond in [tex]N_{2}[/tex] higher in strength than nitrogen to nitrogen bond in [tex]N_{2}H_{4}[/tex]
Lewis dot structures are given below.

Based on the Lewis electron-dot diagrams of N2 and N2H4, N2 has a stronger nitrogen-to-nitrogen bond than N2H4.

The strength of a bond is dependent on the bond length and the bond order. The higher the bond order, the shorter and stronger the bond. Hence triple bonds are stronger than double bonds and double bonds are stronger than single bonds.

Having said that, N2H4 contains single bonds while N2 contains a triple bond. Hence, N2 has stronger nitrogen-to-nitrogen bond compared to N2H4.
