Properties of Water

Question 13 • *STPSB_Environmental Science 2627

Which is a characteristic of the polar water molecule?

Answer
A
a tetrahedral electron domain geometry with covalently bonded atoms
B
a tetrahedral electron domain geometry with ionically bonded atoms
C
a linear shape with polar covalent bonds
D
a linear shape with polar ionic bonds

Explanation

In H₂O, oxygen has two bonding pairs and two lone pairs, making four electron domains arranged tetrahedrally. The O–H bonds are covalent, not ionic; water’s molecular shape is bent, even though its electron-domain geometry is tetrahedral. Thus, the correct choice is “a tetrahedral electron domain geometry with covalently bonded atoms.”
