A compound 'A' having the molecular formula C5H12O, on oxidation gives a compound 'B' with molecular formula C5H10O. Compound 'B' gave a 2, 4-dinitrophenylhydrazine derivative but did not answer haloform test or silver mirror test. The structure of compound 'A' is
CH3-CH2-CH2-CH2-CH2-OH
CH3-CH2-CH2H-CH3
CH3-CH2-H-CH2-CH3
CH3-CH2-H-CH2-OH
C.
CH3-CH2-H-CH2-CH3
Since, compound B gave a 2, 4-dinitrophenylhydrazine derivative but did not answer halogen or silver mirror test, it must contain a -C=O group, but it is neither a methyl ketone nor an aldehyde.
Although compound B is obtained by the oxidation of compound A, having molecular formula C5H12O, so compound A must be a secondary alcohol.
