Q6 / 160 · AP EAMCET 2022 (05 Jul Shift 2) · Chemistry

The tetra atomic molecules/ions with different shapes are

  • A
    $\mathrm{Tecl}_4, \mathrm{SeF}_4$
  • B
    $\mathrm{CH}_4, \mathrm{PCl}_4^{+}$
  • Correct answer
    C
    $\mathrm{SF}_4, \mathrm{NH}_4^{+}$
  • D
    $\mathrm{SiH}_4, \mathrm{CCl}_4$

Solution

$\mathrm{TeCl}_4, \mathrm{SeF}_4$ - square planar; $\mathrm{CH}_4, \mathrm{PCl}_4^{+}-$Tetrahedral $\mathrm{SF}_4$ - square planar, $\stackrel{+}{\mathrm{N}} \mathrm{H}_4$-Tetrahedral $\mathrm{SiH}_4, \mathrm{CCl}_4-$ Tetrahedral.

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