An element 'A' exists as a yellow solid in standard state .It forms a volatile hydride
'B' which is a foul smelling gas and is extensively used in qualitative analysis of
salts .When treated with oxygen , 'B' forms an oxide 'C' which is a colourless,
pungent smelling gas .This gas when passed through acidified KmnO4 solution
decolurises it .'C' gets oxidised to another oxide 'D' in the presence of a
heterogenous catalyst .Identify A,B,C,D and also give the chemical equation of
reaction of 'C' with acidified KmnO4 solution and for conversion of 'C and 'D' .
