The correct increasing order of trans-effect of the following species

1.	The correct increasing order of trans-effect of the following species isA. `NH_(3)gtCN^(-)gtBr^(-)gtC_(6)H_(5)^(-)`B. `CN^(-)gtC_(6)H_(5)^(-)gtBr^(-)gtNH_(3)`C. `Br^(-)gtCN^(-)gtNH_(3)gtC_(6)H_(5)^(-)`D. `CN^(-)gtBr^(-)gtC_(6)H_(5)^(-)gtNH_(3)`
Answer» Correct Answer - B Trans effect is the effect of a coordinated group upon the rate of substitution at the position trans to itself in a square or octahedral complex. As the rate of substitution of the trans ligand increases, the intensity of trans effect also increases. Thus, correct order is, `CN^(-)gtC_(6)H_(5)^(-) gtBr^(-)gtNH_(3)`
