Question

Sketch water molecules and hydrogen bonds between them (dotted line).

A) Oxygen and two hydrogen atoms form a linear structure.
B) Hydrogen bonds form between oxygen atoms of different water molecules.
C) Each water molecule can form up to four hydrogen bonds.
D) The dotted lines represent covalent bonds within a water molecule.

Answer 1

Water molecules form linear structures with covalent bonds within the molecule. Hydrogen bonds form between oxygen atoms of different water molecules. Each water molecule can form up to four hydrogen bonds.

Step-by-step explanation:

Water molecules consist of one oxygen atom bonded to two hydrogen atoms. The arrangement is linear, with the oxygen atom in the center and the hydrogen atoms on either side. These covalent bonds within the water molecule are represented by solid lines.

Hydrogen bonds form between oxygen atoms of different water molecules. They occur due to the weakly positive charge on the hydrogen atoms and the weakly negative charge on the oxygen atoms. These hydrogen bonds are indicated by dotted lines.

Each water molecule can form up to four hydrogen bonds. The tetrahedral arrangement of the water molecule allows for the maximum number of hydrogen bonds to be formed.
