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

NH_3 > CN^- > Br^- > C_6H_5^-

CN^- > C_6H_5^- > Br^- > NH_3

Br^- > CN^- > NH_3 > C_6H_5^-

CN^- > Br^- > C_6H_5^- > NH_3

Multiple Choice Options

A NH 3 > CN $-$ _ > Br $-$ _ > C 6 H 5 $-$ _
B CN $-$ _ > C 6 H 5 $-$ _ > Br $-$ _ > NH 3
C Br $-$ _ > CN $-$ _ > NH 3 > C 6 H 5 $-$ _
D CN $-$ _ > Br $-$ _ > C 6 H 5 $-$ _ > NH 3

Step-by-Step Verified Solution

The intensity of the trans-effect as measured by the increase in rate of substitution of the trans ligand) follows the sequence : CN _ > C 6 H 5 _ > Br _ > NH 3
