MCQ
Choose the correct statement
- ✓White or yellow phosphorus is stored under water
- BIgnition temperature of red phosphorus is low
- CBlack phosphorus is non crystalline in nature
- DPhosphorus does not form hydrides
✓
Answer
Correct option: A.
White or yellow phosphorus is stored under water
a
Due to low ignition temperature of white phosphorus, it undergoes oxidation in presence of air which slowly raises its temperature and after a few moments it catches fire spontaneously. Due to this reason, it is stored under water. Ignition temperature of red phosphorus is high. Black phosphorus is crystalline in nature. Phosphorus forms a number of hydrides.
