Which component, if present in paper causes brittleness:
Correct answer: D. Lignin
- A. Chlorine
- B. Cellulose
- C. Sodium hydroxide
- D. Lignin
Explanation
Lignin is the correct answer because it is a complex polymer found in the cell walls of plants, especially in wood, and it provides rigidity to the cell walls. However, lignin also makes paper more brittle over time due to its hydrophobic nature, which causes it to repel water and become less flexible as it ages.
