Options
- Aon hydrolysis gives an oxo-acid of phosphorus which is tribasic
- Bon hydrolysis gives an oxo-acid of phosphorus which is a good reducing agent
- CHas all the five equivalent bonds
- Dexists as an ionic solid in which cation has octahedral structure and anion has tetrahedral structure
Correct answer
A. on hydrolysis gives an oxo-acid of phosphorus which is tribasic
Step-by-step solution
Phosphorus pentachloride on hydrolysis gives an oxo acid of phosphorus which is tribasic. PCl ₅+4 HOH H ₃ PO ₄+5 HCl Here, phosphoric acid ( H ₃ PO ₄ ) is tribasic.
