So in this question, let's look at the type of crystalline solids in the properties and identify the examples given.
00:06
So let's look at ccl3.
00:08
So we have high melting point and high boiling point.
00:11
The liquid is a conductor.
00:13
So therefore, we know that this is ionic because ionic compounds have high melting and boiling points.
00:21
However, they can only conduct electricity as a liquid because in the liquid phase, the ions separate and there are opposite charges and they're able to.
00:30
To carry a charge.
00:33
So let's look at the next one.
00:35
This one has a high melting and boiling point.
00:39
It's an electrical conductor in both solid and liquid.
00:42
Therefore, it's metallic because metallic compounds have delocalized electrons, making them able to conduct electricity in either phase.
00:50
They also have high melting and boiling points as well...
