Easy MCQ +4 / -1 PYQ · JEE Mains 2022

Which of the following pair of molecules contain odd electron molecule and an expanded octet molecule?

  1. A $\mathrm{BCl}_{3}$ and $\mathrm{SF}_{6}$
  2. B $\mathrm{NO}$ and $\mathrm{H}_{2} \mathrm{SO}_{4}$ Correct answer
  3. C $\mathrm{SF}_{6}$ and $\mathrm{H}_{2} \mathrm{SO}_{4}$
  4. D $\mathrm{BCl}_{3}$ and $\mathrm{NO}$

Solution

(A) $\mathrm{BCl}_{3}$ - Even electron molecules <br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $\mathrm{SF}_{6}$ - Expended octet molecules <br/><br/> (B) $\mathrm{NO}$ - Odd electron molecules<br/> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$\mathrm{H}_{2} \mathrm{SO}_{4}$ - Expanded octet<br/><br/> (C) $\mathrm{SF}_{6}-$ Even electron molecules<br/>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;$\mathrm{H}_{2} \mathrm{SO}_{4}$ - Expanded octet <br/><br/> (D) $\mathrm{BCl}_{3}-$ Even electron molecules <br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$\mathrm{NO}$ - odd electron molecules
