The species for which the shapes (geometry) can be predicted by VSEPR theory is/are(A) $\left[\mathrm{PtCl}_{4}\right]^{2-}$ (B) $\left[\mathrm{TeCl}_{6}\right]^{2-}$ (C) $\mathrm{PF}_{3}$ and $\mathrm{SF}_{6}$
(a)A and C
(b)B and C
(c)C only
(d)A and B
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
VSEPR works for main-group species like PF₃ and SF₆; it fails for the d⁸ square-planar [PtCl₄]²⁻ and for [TeCl₆]²⁻, whose 'inert' lone pair leaves it regular octahedral.
