Correct answer: B. conc. HNO3
- A. P4O10
- B. conc. HNO3
- C. conc. H2SO4
- D. conc. H3PO4
Explanation
Concentrated sulfuric acid, phosphoric acid, and phosphorus pentoxide are all effective dehydrating agents used to convert alcohols to alkenes. Concentrated nitric acid (HNO3) is a strong oxidizing agent and is not typically used for dehydration.
