Recognizing the Properties of Water

Water has a "bent" geometry. Which explanation

does not explain why?

o Water's oxygen has unbonded electron pairs

that repel each other.

Water can form hydrogen bonds.

Electrons are evenly distributed in the water

molecule.

DO NE

1. c

2. b

The first option does explain waters bent geometry. The Oxygen atom in water has two pairs of unbonded electrons. They are repelling each other. Water can form hydrogen bonds due to the electron distribution not the geometry. However the last statement is more untrue. Electrons are drawn to the more electronegative atom which is oxygen so that where they spend the most time.

Therefore the last one being untrue does not explain the geometry.
