Question

12 choose the best answer based on the lewis structure. how many lone pairs are represented in this lewis structure?

Explanation:

For Question 11:

VSEPR Theory is the concept that focuses on the repulsion between valence electron pairs around a central atom, which dictates that these pairs arrange to be as far apart as possible to minimize repulsion. The other options describe related but distinct concepts: Lewis structures show bonding and lone pairs, electron dot notation is a type of Lewis representation, and molecular geometry is the result of VSEPR interactions.

For Question 12:

In the given Lewis structure of water ($H_2O$), the central oxygen atom has two pairs of non-bonding (lone) electrons, visible as the unpaired dot groups on the oxygen.

Answer:

1. C. VSEPR Theory
2. 2
