They vary- most decompose into smaller units which may be molecules or atoms or free radicals. there is no hard and fast rule- usually we are talking of very high temperature gases.

Does covalent structures have high or low boiling points?
It depends on the type of structure; simple covalent structures (like water) generally have low boiling points, while giant covalent structures (like diamond) have high boiling points.
what type of bonds form lattice structures?
Ionic bonded always. Also giant covalent structures- like diamond and silicon dioxide. It is NOT just ionic compounds!
Can carbon form covalent bonds with other carbon atoms?
Indeed they can. A common example of Carbon covalently bonding with carbon is in what we refer to as Giant Covalent Structures, which are multiple of an atom bonded together in a set, lattice-like shape. Examples of giant covalent structures made from carbon are diamond where the atoms are arranged in a pyramid shape, and graphite, where they are arranged in flat layers.
Why graphite is soft and greasy and good conductor of electricity?
Unlike most Giant Covalent Structures like diamond that form four covalent bonds, Graphite only forms 3, meaning it has a free electron meaning that graphite can conduct electricity.
Type of covalent bonding that is found in the diamond?
The type of covalent bond in a diamond is a 'giant covalent' bond in a crystalline structure. Actually, I think it's called a covalent network solid. I don't think chemists and physicists would like to use a layman's term like "giant".

What is (covalent) compound?
COVALENT
Why does silicon can form giant structures?
Silicon (like carbon) can form covalent bonds, it forms a giant molecule with the diamond structure. Silicon dioxide is also a giant structure with polar covalent bonds. Silica reacts with basic oxides to form silicates- and these are generally giant structures, polar covalent bonds again, that form a very large proportion of the minerals in the earths crust.
Can giant covalent structures conduct electricity when molten?
Some do- for example molten silicon conducts like ametal when molten.

What structure do covalent bonds create?
Covalent bonds are formed by electron sharing between atoms. They create structures called molecules.
Do giant covalent substance dissolve in water?
No, they don't. As giant covalent substances are non-polar, means having no dipole moment. Only polar or substances having charges like ionic compounds are soluble in water.
Why do simple covalent bonds have low melting and boiling point?
It's due to the facts that simple covalent bonds like single bonds are weaker and longer than others bonds with tighter interactions like pi bonds (double bonds) or ionic bonds. Once the heat is turned up it excites the electrons to move from their bonded positions and the bond breaks
What properties do giant covalent structures have?
A giant covalent structure is an element made with very strong bonds between the atoms too create various materials. A couple of examples are Diamond and Buckminster Fullerine. Graphite is also one but has weak bonds aswell. like...
