Polyethylene Glycols are used in the preparation of which type of detergents?
Correct answer: C. Non-ionic detergents soap
- A. Cationic detergents
- B. Anionic detergents
- C. Non-ionic detergents soap
- D. All of above
Explanation
Polyethylene glycol has long chains with water-attracting ether and hydroxyl groups, so it is used to make non-ionic detergents that clean without forming ions in water. The likely trap is option d, which incorrectly assumes polyethylene glycol is used equally in cationic and anionic detergents.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
