Question
Which of the following compounds show optical isomerism ?
1. cis - [Co(NH3)4 Cl2]+ 2. trans - [Co(en)2Cl2]+
3. cis - [Co(en)2Cl2]+ 4. [Co(en)3]3+
Select the correct answer using the codes given below :
1. cis - [Co(NH3)4 Cl2]+ 2. trans - [Co(en)2Cl2]+
3. cis - [Co(en)2Cl2]+ 4. [Co(en)3]3+
Select the correct answer using the codes given below :
Options
A.1 and 2
B.2 and 3
C.3 and 4
D.1, 3 and 4
Solution
(1) cis - [Co(NH3)4 Cl2]+ has plane of symmetry as well as centre of symmetry ; so optically inactive.
(2) trans - [Co(en)2Cl2]+ has plane of symmetry as well as centre of symmetry ; so optically inactive.
(3) cis - [Co(en)2Cl2]+ lacks plane of symmetry as well as centre of symmetry ; so optically active.
(4) [Co(en)3]3+ lacks axis of internal rotation ; so optically active.
(2) trans - [Co(en)2Cl2]+ has plane of symmetry as well as centre of symmetry ; so optically inactive.
(3) cis - [Co(en)2Cl2]+ lacks plane of symmetry as well as centre of symmetry ; so optically active.
(4) [Co(en)3]3+ lacks axis of internal rotation ; so optically active.
