MCQ
An organic compound $X$ is oxidized by using acidified $\ce{K_2Cr_2O_7}.$ The product obtained reacts with Phenyl hydrazine but does not answer the silver mirror test. The possible structure of $X$ is:
  • ✓
    $\ce{(CH_3)_2CHOH}$
  • B
    $\ce{(CH_4)_2CH_3OH}$
  • C
    $\ce{CH_3CHO}$
  • D
    $\ce{CH_3CH_2OH}$
✓

Answer

Correct option: A.
$\ce{(CH_3)_2CHOH}$
 Secondary alcohol on oxidation forms ketone which reacts with hydrazine bus doesn't gives a silver mirror test.
