Following table compares properties of red phosphorus and white phosphorus. Whic
Following table compares properties of red phosphorus and white phosphorus. Which is incorrect comparison?
- A. Red- Nontoxic and has polymeric structure; White - Toxic, waxy discrete tetrahedral \( P_{4} \) molecule
- B. Red - Discrete tetrahedral \( P_{4} \) molecule; White - Polymeric structure
- C. Red - High m.p., less reactive; White - Low m.p., more reactive
- D. Red - Shows no phosphorescence in air; White - Shows phosphorescence in air
Step-by-step solution
Red phosphorus has a polymeric structure, while white phosphorus consists of discrete tetrahedral P4 molecules. Option B reverses these properties, making it the incorrect comparison.
