JEE Main 2019 (10 Jan Shift 2)
Question
A reaction of cobalt chloride and ethylenediamine in a mole ratio generates two isomeric products (violet-coloured) and (green-coloured). can show optical activity, but, is optically inactive. What type of isomers do and represent?
Choose an option

Correct answer
DGeometrical isomers
Step-by-step explanation
The coordination number of cobalt is .
The mole ratio of and is .
Hence,
The complex formed shows geometrical isomerism.
The complex exists as cis and trans isomers among which the trans isomer is optically inactive.
