Sapling Question 11

[Talia Dini - 3I]

On the sapling homework, I was supposed to arrange the following bonds according to length: N-I, N-O, N-H. I am unsure, however, why the bond N-H is shorter than the bond N-O. Could someone please explain this to me?

[Mackenzie Van Val 3E]

H is a smaller atom than O, which means that the bond between it and N will be shorter. In addition, there is a higher difference in electronegativity between N and H than N and O, which means that N and H will pull closer together.

[Sondia Luong 1C]

N-H is shorter than the bond N-O because hydrogen only has 1 electron, while oxygen has a total of 8 electrons. This means the hydrogen is a smaller atom, so there is less distance between the hydrogen and nitrogen atom. On the other hand, since oxygen is larger and has more electrons, the distance between N and O will be longer.

[Maryeli Garay 2H]

Hydrogen is a smaller atom than oxygen, so the bond between H and N is gonna be shorter. :)

[AntonioZarich2E]

Bond length is determined by size and electronegativity. Hydrogen is smaller than O, so the N-H bond will be shorter than the N-O bond.

[Queena Chu 3E]

Since H is smaller than O, the bond between H and N is shorter than the bond between H and O.
