a) Acetaldehyde under goes oxidation to form acetic acid.
`CH_(3)CHO overset((O))to CH_(3)COOH`
b) Acetane undergoes oxidation to form acetic acid.
`CH_(3)COCH_(3) underset(K_(2)Cr_(2)O_(7)//H^(+))overset((O))to CH_(3)COOH`
c) Acetophenone undergoes oxidation to form benzoicacid and chloroform
`C_(6)H_(5)-CO-CH_(3) underset(NaOCl, H_(3)O^(+))overset((O))to C_(6)H_(5)COOH + CHCl_(3)`
