In table below, there are descriptions of an experiment on samples of three different chemical compounds. Decide whether the compound is ionic or molecular, if you can. If there is not enough information to decide, choose can't decide in the third column.
Compound Description Ionic or Molecular
1 Compound 1 is a light gray solid made of overlapping
hexagonal crystals. When heated gently it starts to soften
and develop an unpleasant smell about 50 °C. above
room temperature.
2 Compound 2 is a deep red solid with a noticeable
unpleasant smell. It dissolves slightly in water, and
a solution of 2 g in 100 mL of water doesn't change the
electrical conductivity of the water.
3 Compound 3 is a clear liquid with a strong smell. If
heated gently it boils at 115. °C.

Molecular compounds typically exhibit covalent compound characteristics. They are pure substances formed when atoms are linked together by sharing electrons while ionic compounds are formed due to the transfer of electrons. Molecular substances tend to melt at moderately warm temperatures (i.e. 50° C) and it is overlapping as seen in compound 1, which makes it to be molecular in nature.

Molecular compounds are not affected by conductivity, hence they are electrically neutral.

Molecular compounds have a strong smell and have freezing and boiling point at accessible temperatures. A clear liquid at room temperature which has a fruity strong smell can be an organic compound. These organic compounds made up of covalent bonds and are molecular in nature.
