likoan [24]

Answer:

Compound 1 is molecular

Compound 2 is ionic

Compound 3 can't really be decided

An ionic substance conducts electricity in solution or in molten state but never in the pure solid state, has a high melting and boiling point and has a dull appearance most times.

Compounds 1 shows the properties of molecular substances hence it are designated as such.

On the other hand, compound 2 shows the properties of an ionic substance and is also designated as such.

We can't really decide on compound 3 because it shows some properties of ionic substances and some properties of molecular substances.
