Coordination Compounds Question 15
Question 15 - 2024 (30 Jan Shift 2)
Number of complexes which show optical isomerism among the following is _________.
cis $-\left[\mathrm{Cr}(\mathrm{ox}){2} \mathrm{Cl}{2}\right]^{3-},\left[\mathrm{Co}(\mathrm{en})_{3}\right]^{3+}$,
cis $-\left[\mathrm{Pt}(\mathrm{en}){2} \mathrm{Cl}{2}\right]^{2+}$, cis $-\left[\mathrm{Co}(\mathrm{en}){2} \mathrm{Cl}{2}\right]^{+}$,
trans $-\left[\mathrm{Pt}(\mathrm{en}){2} \mathrm{Cl}{2}\right]^{2+}$, trans $-\left[\mathrm{Cr}(\mathrm{ox}){2} \mathrm{Cl}{2}\right]^{3-}$
Show Answer
Answer (4)
Solution
cis $-\left[\mathrm{Cr}(\mathrm{ox}){2} \mathrm{Cl}{2}\right]^{3-} \rightarrow$ can show optical isomerism (no POS & COS)
$\left[\mathrm{Co}(\mathrm{en})_{3}\right]^{3+} \rightarrow$ can show (no POS & COS)
cis $-\left[\mathrm{Pt}(\mathrm{en}){2} \mathrm{Cl}{2}\right]^{2+} \rightarrow$ can show (no POS & COS)
cis $-\left[\mathrm{Co}(\mathrm{en}){2} \mathrm{Cl}{2}\right]^{+} \rightarrow$ can show (no POS & COS)
trans $-\left[\mathrm{Pt}(\mathrm{en}){2} \mathrm{Cl}{2}\right]^{2+} \rightarrow$ can’t show (contains POS & COS)
trans $-\left[\mathrm{Cr}(\mathrm{ox}){2} \mathrm{Cl}{2}\right]^{3-} \rightarrow$ can’t show (contains POS & COS)
