Hydrogen Bonding?

Question

Can there be two hydrogen bonds between two molecules of NH3? For instance, one of hyrdogen from one NH3 molecule bonds through hydrogen bonding with the nitrogen (N) of te second molecule. And then one of the hydrogens from the second molecule connects with the nitrogen atom of the first molecule. Is this possible? Why?


Thanks,

Answer 1

This of what the Ammonia molecule looks like...draw its Lewis structure,

If you have two molecules of Ammonia, the slightly + Hydrogen's will be attracted to the slightly - Nitrogen side of the molecule so it will orient it self to as to form the closest arrangement possible.
However, when the H and N atoms are lined up with each other on different molecules, the other N and H atoms a pointing away from each other.
So no, both sides of two different NH3 molecules will not attract each other at the same time.

Answer 2

not all molecules with capacity lone electrons could make hydrogen bonds. HF makes a linear zig-zag shape with 2 hydrogen bonds. This has to do with the density, molecular weight, and length of the molecule.

Answer 3

i think it's yes.... know why? what if the orientation of the N-H bond of the first NH3 molecule is oriented completely parallel to the N-H bond of the second NH3 molecule then two H-bonding can occur simultaneously on the two molecules of NH3....

best answer?
