The molecule which is NOT hydrolysed by water at $25^{\circ} \mathrm{C}$ is

  • A
    $\mathrm{AlCl}_{3}$
  • B
    $\mathrm{SiCl}_{4}$
  • C
    $\mathrm{BF}_{3}$
  • Correct answer
    D
    $\mathrm{SF}_{6}$

Solution

Due to steric hinderance $\mathrm{SF}_{6}$ is not hydrolysed by $\mathrm{H}_{2} \mathrm{O}$ at $25^{\circ} \mathrm{C}$

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