C3.6 Simple Molecules Flashcards
(7 cards)
1
Q
What is a simple molecule?
A
A small group of atoms joined by covalent bonds.
2
Q
What type of bonding do simple molecules have?
A
Covalent bonding.
3
Q
What are the forces between simple molecules called?
A
Intermolecular forces.
4
Q
Why do simple molecules have low melting and boiling points?
A
Because the intermolecular forces are weak and easy to break.
5
Q
Do simple molecular substances conduct electricity?
Why or why not?
A
No, because they don’t have free electrons or ions.
6
Q
Give two examples of simple molecules.
A
Water (H₂O) and methane (CH₄).
7
Q
What happens to the strength of intermolecular forces as molecules get bigger?
A
They get stronger, so melting and boiling points increase.
