Fifth group elements form hydrides of type AH_3.The hydrides have a lone pair of electrons.The hydrides are reducing in nature and the reducing power is related to the stability of A-H bonds.The hydrides are covalent and low boiling.Their boiling point depends on their ability to form hydrogen bond and their molecular size which which decide the intermolecular forces in the hydrides. Which of the following statements is true ?

Answer» Gas (G) REACTS with conc NaOH to form `OF_2` Pale Blue gas (E) OXIDISES ALKALINE KI to `KIO_3` Pale blue gas (E) in acidic medium reacts with `K_2Cr_2O_7` to form a bright blue coloured compound `(CrO_5)` (B) and (C ) both Solution :(A)`F_2` gives`O_2` gas (C )`H_2O_2` in acidic medium form `CrO_5 , "not" O_3` (B)`KI+3O_3 to KIO_3 + 3O_2` `underset((A))(XeF_2)overset(H_2)tounderset((B))(XE)+underset((C ))(2HF)` `XeF_2+H_2overset(H_2)to+underset((B))(Xe)+underset((C ))(HF)+underset((D))(O_2)` `underset(( D))(3O_2)hArrunderset((E))(2O_3),5O_3+2KOH to 2KO_3`(orange solid)+`5O_2+H_2O` `underset(( C))(HF)+KFtoKHF_2("molten")overset("ELECTROLYSIS")tounderset((G))(F_2)`
