compared with the melting points of ionic compounds, the melting points of molecular solids tend to be
higher
unpredictable
lower
similar

Option (c) is the correct answer.

Explanation:

Molecules of a molecular solid are held together by weak forces like london dispersion forces, dipole-dipole forces.

So, due to weak forces present in these molecules it is easy to break the bond between them. Hence, molecular solids have low melting point.

Whereas in ionic compounds, atoms are held together by strong forces due to the presence of opposite charges on the atoms of the solid.

Therefore, we can conclude that compared with the melting points of ionic compounds, the melting points of molecular solids tend to be lower.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
