Reaction of Cresylic acid with _____________ produces Tricresyl phosphate?
Correct answer: B. Phosphorous oxychloride
- A. Phosphorous pentoxide
- B. Phosphorous oxychloride
- C. Ammonium phosphate
- D. Calcium phosphate
Explanation
Cresylic acid reacts with phosphorus oxychloride, POCl₃, to replace the chloride groups with cresyl groups and form tricresyl phosphate. Phosphorus pentoxide does not provide the required phosphoryl chloride structure directly.
