What is the role of P–H bonds in terms of ionization and basicity in these acids?

Options

  1. AThey are ionizable, increasing basicity
  2. BThey are ionizable, decreasing basicity
  3. CThey are not ionizable and do not affect basicity
  4. DThey are not ionizable, but increase basicity

Correct answer

C. They are not ionizable and do not affect basicity

Step-by-step solution

The paragraph explains that P–H bonds are not ionizable to give H+ and do not play any role in basicity. Only H atoms attached with oxygen in P–OH form are ionizable and contribute to basicity.
