Figure
the reactant $\mathrm{A}$ is

  • Correct answer
    A
    $\mathrm{CH}_{3} \mathrm{CHOHCH}_{3}$
  • B
    $\mathrm{CH}_{3} \mathrm{COCH}_{3}$
  • C
    $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}$
  • D
    $\mathrm{CH}_{3} \mathrm{COOH}$

Solution

$\underset{\text { A }}{\mathrm{CH}_{3} \mathrm{CHOHCH}_{3}} \frac{\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}}{\text { dil.H }_{2} \mathrm{SO}_{4}} \underset{\mathrm{B}}{\mathrm{CH}_{3} \mathrm{COCH}_{3}}$ $\frac{\mathrm{CH}_{3} \mathrm{MgI}}{\mathrm{H}_{2} \mathrm{O}}\left(\mathrm{CH}_{3}\right)_{3} \mathrm{COH}$

Hence, the correct answer is option: 'A'.
