Covalent Bonding Flashcards
When does covalent bonding occur?
Covalent bonding occurs when two non-metals share electrons.
What are covalent molecular substances?
Covalent molecular substances are known as discrete covalent molecules.
What are the intermolecular and intramolecular forces present in this bonding?
The covalent bonding within these molecules (intramolecular forces) are strong.
The bonds between the molecules (intermolecular forces) are weak and easy to break.
Explain why discrete covalent molecules have low melting and boiling points:
The forces that hold the molecules together (intermolecular forces) are weak.
Explain why covalent molecules cannot conduct electricity:
There are no charged particles (electrons or ions) that can move through the substance.
Why they form solids ? (covalent molecular substances)
The forces that hold the molecules together are weak.(intermolecular).
Why do they tend to be malleable instead of shattering?
The forces between the molecules are weak so molecules are easily moved.
Solubility?
Solubility depends on the intermolecular forces.
What are molecular solids?
Molecular solids are discrete covalent molecules that are solids at room temperature.
