Which of the compound show optical isomerism ? 1.`cis-[Co(NH_(3))_(4)C

1.	Which of the compound show optical isomerism ? 1.`cis-[Co(NH_(3))_(4)Cl_(2)]^(+) " "2.trans-[Co(en)_(2)Cl_(2)]^(+)` `3. cis-[Co(en)_(2)Cl_(2)]^(+)" " 4.[Co(en)_(3)]^(3+)` Select the correct answer using the codes given below:A. 1 and 2B. 2 and 3C. 3 and 4D. 1,3 and 4
Answer» Correct Answer - C (1) `cis-[Co(NH_(3))_(4)Cl_(2)]^(+)` has plane of symmetry as well as centre of symmetry , so optically inactive. (2) `trans-[Co(en)_(2)Cl_(2)]^(+)` has plane of symmetry as well as centre of symmetry , so optically inactive. (3 ) `cis-[co(en)_(2)Cl_(2)]^(+)` 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.
