Question

which is an example of a polymer? (1 point)
○ sodium chloride
○ carbon monoxide
○ diamond
○ cellulose

Explanation:

To determine the polymer, we analyze each option:

• Sodium chloride ($\text{NaCl}$) is an ionic compound, not a polymer.
• Carbon monoxide ($\text{CO}$) is a simple covalent compound, not a polymer.
• Diamond is a covalent network solid (allotrope of carbon), not a polymer.
• Cellulose is a polysaccharide, a type of polymer made from repeating glucose units.

Answer:

The option representing a polymer is: cellulose (the option with "cellulose" text).
