Coordination Compounds Question 15
Question 15 - 2024 (30 Jan Shift 2)
Number of complexes which show optical isomerism among the following is _________.
cis $-\left[Cr(ox) _2 Cl _2\right]^{3-},\left[Co(en) _3\right]^{3+}$,
cis $-\left[Pt(en) _2 Cl _2\right]^{2+}$, cis $-\left[Co(en) _2 Cl _2\right]^{+}$,
trans $-\left[Pt(en) _2 Cl _2\right]^{2+}$, trans $-\left[Cr(ox) _2 Cl _2\right]^{3-}$
Show Answer
Answer (4)
Solution
cis $-\left[Cr(ox) _2 Cl _2\right]^{3-} \rightarrow$ can show optical isomerism (no POS & COS)
$\left[Co(en) _3\right]^{3+} \rightarrow$ can show (no POS & COS)
cis $-\left[Pt(en) _2 Cl _2\right]^{2+} \rightarrow$ can show (no POS & COS)
cis $-\left[Co(en) _2 Cl _2\right]^{+} \rightarrow$ can show (no POS & COS)
trans $-\left[Pt(en) _2 Cl _2\right]^{2+} \rightarrow$ can’t show (contains POS & COS)
trans $-\left[Cr(ox) _2 Cl _2\right]^{3-} \rightarrow$ can’t show (contains POS & COS)
