In VSEPR theory, which geometry corresponds to AB2E2 and what is the typical bond angle?

Explanation:
In VSEPR, AB2E2 means the central atom has two bonding pairs and two lone pairs, giving four electron domains around it. The electron-domain arrangement is tetrahedral, but lone pairs take up more space than bonding pairs, so they push the two bonding atoms closer together. That makes the molecular geometry bent (angular) rather than linear, and the bond angle drops from the ideal 109.5° to about 104.5°. This shape and angle are characteristic of water, the classic example of AB2E2.
