What solid is stronger ionic solid or covalent network solids?

Answer 1

Network solids are held together by covalent bonds to each other. They're usually very hard and have high melting points, and are also poor heat and electrical conductors. Think of diamond and graphite. These are covalent network solids.

Molecular solids, on the other hand, are molecules held together by weak intermolecular forces (such as dipole-dipole, ion-dipole, or London dispersion forces). These are usually soft with low melting points, and are also poor conductors of heat and electricity. Some examples of molecular solids would be carbon dioxide and benzene.

The way I think about it, to help it make more sense to me, is that in covalent network solids, each atom is BONDED to all the other atoms around it. In molecular solids, you have completely separate molecules that are just weakly held together by intermolecular forces, they're not actually bonded to each other.

Answer 2

The best answer I can come up with is that covalent molecular are held together by covalent bonds AND intermolecular bonds whereas covalent networks are only held together by covalent bonds. This means that the intermolecular bonds in covalent molecular are easy to break which is why it has a low boiling point.

Covalent networks are all covalently bonded which means they are stronger and have a higher boiling point.

I hope that's right because i have a test on this tomorrow.

Sorry if it is wrong.

Answer 3

Network solids, like diamonds, have strong bonds, high melting points, and are hard. They are held together by hydrogen bonding, dipole-dipole forces, or London Dispersion forces.

Molecular solids, like sugar, have weak bonds, low melting points, and are soft. They are held together by covalent bonding, making them much more stable than molecular solids.

Answer 4

There are differences but these are not necessarily diagnostic. Solubilty in water is a feature of many ionic solids, but not all. Molten ionic solids conduct electricty, molten covalent do not. Ionic solids tend to be more brittle than covalent- but not an easy property to measure!

Answer 5

A molecular solid consistes of discrete molecules. A network covalent solid is "infinite " in size-- the molecule is the size of the sample.

Answer 6

The so-called molecular solid has ionic bonds.
