In case
of ClO2 odd electron is delocalized
over 3 atoms so extent of delocalization of odd electron is higher in
comparison to NO. Hence tendency of demerisation of a NO is faster that of ClO2.

Although electron affinity of chlorine is higher than fluorine, yet fluorine act as better oxidizing agent than chlorine? Explain.
Oxidizing character of elements calculated in aqueous medium while electron affinity is the term related to gaseous state.
Since fluorine possesses small size and high negative charge density thus undergoes more hydration as compared to
chlorine as result of which its hydration energy increases than electron
affinity and thus fluorine takes electron easily in aqueous medium and act as
best oxidizing agent.The another reason of high oxidizing power of fluorine is
its low bond dissociation energy as compare to chlorine.

What is structure of solid Ortho Boric acid ?
Boric
acid mainly exist in polymeric form like tri ,tetra, panta but tri and tetra
meta boric acid are well known, because it's sodium salt (sodium borate,or sodium
tetra borate or disodium tetra borate) is very famous which is called "Borax" or Tincal and commercially named as Jeweller,s of Borax [Na2B4O5(OH)4•8H20
or Na2B4O7•10H2O]
In solid state Boric
[B(OH)3] unit are hydrogen
bonded together into two dimensional sheet.
Borax is uses in
manufacturing of ENAMELS and glazes for pottery and disinfectant in medicine.
