Which type of intermolecular attractions holds ammonia molecules together with other ammonia molecules?

Hydrogen bonds (strongest).Dipole-dipole interactions (weaker than hydrogen bonds).Explanation

There are three major types of intermolecular attractions:

Hydrogen bonds,Dipole-dipole interactions, andLondon dispersion forces.

London dispersion forces exist between all molecules. It is the weakest among the three types of forces.

Dipole-dipole interactions exist between polar molecules. It is stronger than London dispersion forces.

Hydrogen bonds are attractions between

H atoms directly bonded to atoms of N, O, or F; andLone pairs of electrons on other molecules.

Hydrogen bonds is the strongest among the three types of forces.

Consider the structure of an ammonia molecule.

All three H atoms are bonded to an N atom.There is one lone pair of electrons on the central N atom.N-H bonds are highly polar.The shape of the molecule is pyramidal. As a result, dipoles from the three N-H bond remain not balanced. The molecule is overall polar.

As a result, molecules will form both hydrogen bonds and dipole-dipole interactions between them. There's also going to be London dispersion forces. Nonetheless, hydrogen bonds and dipole-dipole interactions will contribute to the majority of attractions between the molecules.

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
