An organic compound containing C, H and O gives red colouration with sodium nitroprusside solution but does not reeduce Tollen's reagent and yields chloroform on treating with NaOH and Cl_(2) .The compound is

A' (C_(6)H_(14)O) is an organic compound which gives blood red colour with ceric ammonium nitrate. It gives iodoform test on treatment with NaOH //i_(2) , salt ofmonobasic acid 'B' is also formed during the reaction. Salt on acidification gives 2,3-dimethyl propanoic acid. What are 'A' and 'B', give their structural formulae ?
