Of the following chemical properties , which one is not one that Covalent compounds DO NOT have ?

a
They share electrons between their elements.

b
They have weaker bonds.

c
They have relatviely higher melting and boiling points.

d
Many of these compounds are usallly liquids or gases at room temperature.

D. They are usually liquids or gases at room temperature.

Explanation:

Covalent compounds have covalent bonds, meaning that they share electrons between elements and have relatively higher melting melting and boiling points due to the strength of their bonds. However covalent bonds are weaker than ionic bonds which is why B is correct. D is the only incorrect one because it is incorrect and contradicts point C. If a substance has a high melting/boiling point than it is much more likely to be solid at room temperature because of the high temperature it needs to pass in order to be a liquid or gas.

Hope this helped!
