Which one of the following reactions will not yield propanoic acid?

• Correct answer
  A

  ${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{Br}+\mathrm{Mg},{\mathrm{CO}}_2$ dry ether $/{\mathrm{H}}_3{\mathrm{O}}^{+}$
• B

  ${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_3+{\mathrm{KMnO}}_4\left(\mathrm{Heat}\right),{\mathrm{OH}}^{-}/{\mathrm{H}}_3{\mathrm{O}}^{+}$
• C

  ${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CCl}}_3+{\mathrm{OH}}^{-}/{\mathrm{H}}_3{\mathrm{O}}^{+}$
• D

  ${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{COCH}}_3+{\mathrm{OI}}^{-}/{\mathrm{H}}_3{\mathrm{O}}^{+}$

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