Among $\mathrm{ClO}_{3}, \mathrm{XeO}_{3}$ and $\mathrm{SO}_{3}$, species with pyramidal shape is/are?
(a)$\mathrm{ClO_3^{-}}$ and $\mathrm{XeO_3}$
(b)$\mathrm{XeO_3}$ and $\mathrm{SO_3}$
(c)$\mathrm{ClO_3^{-}}$ and $\mathrm{SO_3}$
(d)$\mathrm{SO}_{3}$
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
ClO₃⁻ and XeO₃ have one lone pair on the centre (AX₃E, pyramidal); SO₃ is trigonal planar (a).
