Question

Which are true statements among the following ?
(A) $P{H}_5$ and $BiC{l}_5$ do not exist
(B) Bond order of $C{O}_3^{2-}$ is 1.33
(C) $Se{F}_{4}andC{H}_4$ have same shape
(D) $I_3^{+}$ has bent geometry
(E) The number of $P_{\pi }-d_{\pi }$ bonds in $S{O}_2\&S{O}_3$ are same

• A. A & C
• B. A, B & E
• C. A, B & D
• D. All the above

Answer 1

The correct option is C A, B & D

$P{H}_5$ and $BiC{l}_5$ are does not exist because overlapping of orbitals are not stable.Bond order of $C{O}_3^{2-}$ is 1.33. Shape of $Se{F}_4$ is pseudo-trigonal bipyramidal and the shape of $C{H}_4$ is tetrahedral. $I_3^{+}$ has $s{p}^3$ hydrogen with bent shape. The number of $p_{\pi }-d_{\pi }$ bonds in $S{O}_2\&S{O}_3$ are not the same
