A compound A (C6H12O6) is oxidised by bromine water into monobasic acid. It also reduces Tollen's reagent and reacts with HCN to give a compound B which on hydrolysis gives a compound C. On treating C with HI / red P, n-heptanoic acid is obtained. Compound A on treatment with excess phenyl hydrazine gave D-glucosazone. Name the compound A and draw its cyclic form.
