JEE Main 2026 — 6 April, Evening Shift — Question 47

Given below are two statements:

Statement I: The number of compounds among SO2,SO3,SF4,SF6\mathrm{SO}_{2}, \mathrm{SO}_{3}, \mathrm{SF}_{4}, \mathrm{SF}_{6} and H2 S\mathrm{H}_{2} \mathrm{~S} in which sulphur does not obey the Octet rule is 3 .

Statement II : Among [H2O,ClF3,SF4],[NH3\left[\mathrm{H}_{2} \mathrm{O}, \mathrm{ClF}_{3}, \mathrm{SF}_{4}\right],\left[\mathrm{NH}_{3}\right., BrF5,SF4],[BrF5,ClF3,XeF4]\left.\mathrm{BrF}_{5}, \mathrm{SF}_{4}\right], \quad\left[\mathrm{BrF}_{5}, \quad \mathrm{ClF}_{3}, \quad \mathrm{XeF}_{4}\right] \quad and [XeF4\quad\left[\mathrm{XeF}_{4}\right., ClF3,H2O]\left.\mathrm{ClF}_{3}, \mathrm{H}_{2} \mathrm{O}\right], the number of sets in which all the molecules have one lone pair of electrons on the central atom is 1 .

In the light of the above statements, choose the correct answer from the options given below :

  1. Option A:

    Both Statement I and Statement II are true

  2. Option B:

    Both Statement I and Statement II are false

  3. Option C:

    Statement I is true Statement II is false

  4. Option D:

    Statement I is false Statement II is true

    Correct

Answer: D

Step-by-step solution

SO2,SO3,SF6&SF4\mathrm{SO}_{2}, \mathrm{SO}_{3}, \mathrm{SF}_{6} \& \mathrm{SF}_{4} do not follow octet rule NH3,BrF5,SF4\mathrm{NH}_{3}, \mathrm{BrF}_{5}, \mathrm{SF}_{4} have one lone pair on central atom ClF3,XeF4&H2O\mathrm{ClF}_{3}, \mathrm{XeF}_{4} \& \mathrm{H}_{2} \mathrm{O} have two lone pair on central atom.
