The type of isomerism shown by the complex [cocl2(en)2]is:
Hello,
The complex [cocl2(en)2] shows geometrical isomerism .
It has a cis and trans form due to the different possible spatial arrangements of the two chloride ligands around the central cobalt atom. The cis-isomer has both chlorides next to each other, while the trans-isomer has them opposite to each other.
Hope it helps !
