Question

the picture shows the formation of an ionic compound. what is the name of the compound

options: ammonia, nitrogen tetrahydride, nitrogen monochloride, ammonium chloride

intermolecular forces of attraction consist of
options: dipole - dipole forces and ionic bonds, a metal and a nonmetal, dipole - dipole forces and london forces, ionic and covalent bonds

Explanation:

First Question (Ionic Compound Name)

The cation is $\ce{NH_4^+}$ (ammonium ion) and the anion is $\ce{Cl^-}$ (chloride ion). Ionic compounds are named by combining the cation name and anion name. Ammonium (from $\ce{NH_4^+}$) and chloride (from $\ce{Cl^-}$) form ammonium chloride. Ammonia is $\ce{NH_3}$, nitrogen tetrahydride is incorrect naming for this, and nitrogen monochloride is not the case here as the cation is ammonium, not nitrogen - based in a simple binary way.

Second Question (Intermolecular Forces)

Intermolecular forces are forces between molecules. Ionic bonds (between ions in an ionic compound, intra - or inter - formula unit in some cases but not typical intermolecular), covalent bonds (intramolecular, within a molecule), and "a metal and a nonmetal" (describes ionic compound formation, not intermolecular forces) are not intermolecular forces. Dipole - dipole forces (between polar molecules) and London forces (dispersion forces, between all molecules) are intermolecular forces.

Answer:

D. ammonium chloride
