(i) $N_3^-, XeF_2$
(ii) $[ICl_4]^-, [PtCl_4]^{2-}$
(iii) $[ClF_2]^+, [ICl_2]^-$
(iv) $XeO_3, SO_3$

• A. (i) & (ii) only
• B. (i) & (iii) only
• C. (i), (ii) & (iii) only
• D. (ii), (iii) & (iv) only

Answer 1

Answer: (B)

(i) $N_3^- \to $ linear, $XeF_2\to$ linear
(ii) $ICl_4^- \to$ Square planar, $[PtCl_4]^{2-} \to $ Square planar
(iii) $ClF_2^+ \to$ Bent, $ICl_2^- \to$ linear
(iv) $XeO_3 \to $ Trigonal pyramidal, $SO_3\to$ Trigonal planar
