Question:
Which of the following phosphorus is the most reactive?
Which of the following phosphorus is the most reactive?
Show Hint
More strain → more reactivity.
Updated On: Apr 23, 2026
- Red phosphorus
- White phosphorus
- Scarlet phosphorus
- Violet phosphorus
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Reactivity depends on structure and strain
Step 1: White phosphorus has P$_4$ tetrahedral structure.
Step 2: It has high angle strain (60$^\circ$).
Step 3: High strain makes it highly reactive.
Step 4: Other forms are more stable (polymeric).
Conclusion:
Most reactive = White phosphorus
