Which kind of isomerism is exhibited by octahedral `[Co(NH_(3))_(4)Br_(2)]CI` ? .

Options

A. Geometrical and ionisation
B. Geometrical and optical
C. optical ionisation
D. Geometrical only

Answer

A

Explanation

Octahedral `[Co(NH_(3))_(4) Br_(2)]Cl` shows ionisation and geometrical isomerism
`[Co(NH_(3))_(4)Br_(2)]ClhArr[Co(NH_(3))_(4)Br_(2)]^(+)+Cl^(-)`
` [Co(NH_(3))_(4)BrClhArr[Co(NH_(3))_(4)BrCl]^(+)+Br^(-)`
in geometrical isomerism , coordination number of central metal atom (cobalt ) is six and shape is octahedral , so it shows following geoetrical isomers .
