Consider the following sequence of reactions Isopropyl benzene $\xrightarrow{\mathrm{O}_2} x \xrightarrow[\mathrm{H}_2 \mathrm{O}]{\mathrm{H}^{+}}$ $+z$ The incorrect statement about z is

• A

  z gives yellow precipitate of $\mathrm{CHI}_3$ with $\mathrm{NaOH}+\mathrm{I}_2$ solution
• B

  z gives isopropyl alcohol on reduction with $\mathrm{H}_2$ in the presence of Pd catalyst
• Correct answer
  C

  z on reaction with $\mathrm{CH}_3 \mathrm{MgBr}$ followed by hydrolysis gives $2^{\circ}$ alcohol
• D

  $z$ does not give positive test with Fehling's reagent

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