Oxoacids of Phosphorus

Phosphorus forms following two series of oxoacids-

(1) Phosphorus series                                    

(2) Phosphoric series

In all these oxoacids of phosphorus, the phosphorus atom is sp3 hybridized and remains tetrahedrally surrounded by other atoms. These acids contain at least one P=O and one P-OH. Those oxoacids in which phosphorus has lower oxidation states also contain either P-H bonds or P-P bond, but not both. Here, the hydrogen atoms of the O-H group are ionizable and therefore, are acidic in nature. The number of such hydrogen atoms corresponds to the basicity of the acid. On the other hand, the hydrogen atoms attached directly to the phosphorus atom are non-ionizable and therefore, non-acidic in nature. These hydrogen atoms are responsible for the reducing nature of the acid.

Important Tips for Preparation of NEET/IIT-JEE

  • Select a good mentor for all the subjects. Several educational channels and the best mentors of Physics, Chemistry, and Biology are available on YouTube for free. You may follow one of them for all the subjects rather than wandering here and there.
  • Centralize your study to the NCERT books and one reference book each for Physics, Chemistry, and Biology. Don’t follow too many books otherwise, you would not be able to complete your syllabus. Always remember, different books differ being only nineteen or twenty in text quality, but never differ of being nineteen and twenty-five. 
  • Follow quality notes of a good mentor for all the subjects. Don’t run behind the brand, but run behind the concise and effective notes of your mentor.
  • Make your own capsule notes for revision.
  • Maintain consistency and regularity in your preparation.
  • Revise the prepared topics regularly. Always remember, revision is not a waste of time but it makes you perfect. Always keep in mind that, “Revision is division” i.e. Revision improves your marks and ultimately your rank in the final selection.
  • Solve practice problems and previous year’s papers in the specified time frame. It would help you to finish your paper timely in the final examination.
  • Always be confident in your preparation but never be overconfident. Always read the question carefully and then answer. You usually make mistakes in overconfidence and it has to be reduced.
