[Co(NH3)Cl(en2)]2+shows two geometrical isomers cis and trans. Which of the following statement is correct?]
A
Trans – isomer will show optical isomerism.
B
Cis – isomer will show optical isomerism.
C
Both trans and cis-isomers will show optical isomerism.
D
Neither cis nor trans-isomer will show optical isomerism.
Answer
Cis – isomer will show optical isomerism.
Explanation
Solution

Trans - [Co(NH3)Cl(en)2]2+has a plane of symmetry and hence it is optically inactive.
