N2f2 Lewis Structure

N2f2 Lewis Structure

Please help with the chemical relationship !!!? 3

Use the Lewis structure to illustrate the variation in the length of the nitrogen nitrogen bond in the table ...

Molecule: N2H4 N2F2 N2

Length of NN connection: 1.45 1.25 1.1

Thank you very much! I will give you a better answer!

I'll give you the Lewis structure, left to right ...

Lewis structure of N2H4 ...

The skeletal structure is H N N H, the other 2 H come directly from N. So they end up in unique pairs with each N.

Lewis structure of N2F2 ...

F N = N F

Lewis structure of N2 ...

It's easy, just two ns with a triple bond between them.

.

However, triple bonds are stronger than double bonds, which in turn are stronger than single bonds.

The higher the bond strength, the shorter the bond length.

Therefore, the bond length increases in sequence ... N2> N2F2> N2H4

I can help you...!

N2f2 Lewis Structure

N2 is the first because it has a triple bond, it is the strongest bond, so they have a deep connection. We have N2F2, the double bond between Ns, still strong, but a little less, so a little less strong. Fs also removes electrons from Ns and their bonds, because F is electronegative, which can have the effect of weakening the double bond. N2H4, single bond, weak, long.
