Which of the following complexes is likely to show optical activity?a)...
Explanation:
Optical Activity in Coordination Complexes:
- Optical activity in coordination complexes is observed when the complex lacks a plane of symmetry.
- A lack of symmetry results in the possibility of different spatial arrangements of ligands around the central metal atom, leading to the existence of enantiomers.
Analysis of Given Complexes:
a) trans-[Co(NH)Cl]
- This complex has a trans geometry, which implies a plane of symmetry. Therefore, it will not show optical activity.
b) [Cr(HO)3+]
- This complex does not have a specific geometry mentioned, but it is likely octahedral. However, the presence of water ligands does not create a lack of symmetry, so it will not exhibit optical activity.
c) cis-[Co(NH)(en)]3+
- This complex has a cis geometry, which lacks a plane of symmetry. The presence of ethylenediamine (en) ligands in a cis arrangement results in the absence of mirror planes, making this complex likely to show optical activity.
d) trans-[Co(NH)(en)]3+
- This complex, although having ethylenediamine (en) ligands, is in a trans geometry. The trans arrangement introduces a plane of symmetry, preventing the complex from exhibiting optical activity.
Therefore, the complex cis-[Co(NH)(en)]3+ is likely to show optical activity due to its lack of a plane of symmetry, allowing for the existence of enantiomers.
