Question

Dawg Tag: 1. In the molecule methanol (CoH4). which atom will be in the center of the skeleton of the Lewis structure? 2. What is the name given to multiple Lewis structures that describe the same molecule? 3. If two or more Lewis structures are possible to represent a molecule, what criterion is used to determine which structure or structures is preferred? 4. What is the shape of a molecule with three atoms bound and one lone pair of electrons on the central atom? 5. What is the shape of a molecule with the 2 lone pairs and 3 atoms bound to the central atom? 6. What is the shape of a molecule with one atom and 2 lone pairs on the central atom? 7. What is the shape of a CO2 molecule? 8. What is the shape of NH, molecule? 9. If a central atom is making 5 bonds with 5 ther atoms, what is the orbital hybridization of that central atom?

Explanation / Answer

Q1.

There is not a single center, we must include Carbon and Oxygen... Typically, we choose Carbon since it has 4 valence electron, which is more flexible to work with

Q2

For a molecule which could be described in multiple Lewis structure, this is called a RESONANCE structure

Q3

We use formal charges, the most stable will be the onw with least charge overall

Q4

Let

AB3E1...

So this will appear to have a tetrahedrical shape, but the geometrical shape we will have is a

trigonal pyramid, due to the lone pairs repulsion
