Sum of $$\pi$$-bonds present in peroxodisulphuric acid and pyrosulphuric acid is ___________
The number of non-ionisable protons present in the product B obtained from the following reactions is ___________.
$$ \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+\mathrm{PCl}_{3} \rightarrow \mathrm{C}_{2} {\mathrm{H}_{5} \mathrm{Cl}+\mathrm{A}} $$
$$\mathrm{A}\,{+}\, \mathrm{PCl}_{3} \rightarrow \mathrm{B}$$
Compound 'P' on nitration with dil. HNO3 yields two isomers (A) and (B). These isomers can be separated by steam distillation. Isomers (A) and (B) show the intramolecular and intermolecular hydrogen bonding respectively. Compound (P) on reaction with conc. HNO3 yields a yellow compound 'C', a strong acid. The number of oxygen atoms is present in compound 'C' _____________.
Consider the following reactions:
PCl3 + H2O $$\to$$ A + HCl
A + H2O $$\to$$ B + HCl
The number of ionisable protons present in the product B is _______________.
