Molecular structure models Flashcards
1
Q
What does Lewis structure depicts as a model?
A
It gives an idea of how the electrons are distributed within a molecule.
However, it can not tell us the shape of the molecule.
2
Q
What are resonance structures?
A
It is an alternative way of drawing a molecule to show delocalized electrons.
The electrons are spread over several atoms rather than being confined to one bond.
3
Q
True/False. The resonance hybrid is less stable than any individual resonance structures.
A
False
Resonance hybrid is more stable due to the distribution of electron density across multiple atoms.
4
Q
What is the shape of water molecule?
A
Tetrahedral
Because it has two bonding pairs and two lone pairs.
5
Q
What are the common geometries in VSEPR Theory?
A
- Linear
- Bent
- Trigonal planar
- Tetrahedral
Bond angles are associated with each geometry.
