Stearic acid and polyethylene glycol react to form which one of the following soap/s detergents ?
  1. (A)Cationic detergent
  2. (B)Soap
  3. (C)Anionic detergent
  4. (D)Non-ionic detergent✓ Correct

Answer: (D)

Solution

Stearic acid (a fatty acid) reacts with polyethylene glycol (a polyol) to form an ester. This product is a non-ionic detergent because it lacks any charged groups—it has only ester linkages and ether linkages. Non-ionic detergents are characterized by the absence of ionic groups. Therefore, option (D) is correct.
