Q21Assertion & reason
A complex of the type [M (AA)2 X2] is known to be optically active. What does this indicate about the structure of the complex? Give one example of such complex. (3)
Show answer
Since complex of the type [M(AA)2 X2] is optically active it indicates that 2+ complex has cis-octahedral structure. e.g. cis-[Pt(en)2(Cl) 2] or + cis-[Cr(en)2(Cl)2] .
