Question: The correct order of ligands in the trans-directing series is

Options:

A) $C N^{-} > C H_{3}^{-} > N O_{2}^{-} > B r^{-}$

B) $C N^{-} > B r^{-} > N O_{2}^{-} > C H_{3}^{-}$

C) $B r^{-} > N O_{2}^{-} > C N^{-} > C H_{3}^{-}$

D) $C H_{3}^{-} > C N^{-} > N O_{2}^{-} > B r^{-}$

Show Answer

Answer:

Correct Answer: A

Solution:

The trans-effect may be defined as the labelization of ligands trans- to the other trans-directing ligand.

[Note: The order of ligands in the trans- directing series is as follows: $C N^{-} \tilde{} C O \tilde{} N O \tilde{} H^{-} > C H_{3}^{-} \tilde{} S C {(N H_{2})}_{2} \tilde{}$

$P R_{3} > S O_{3} H > N O_{2}^{-} \tilde{} I^{-} \tilde{} S C N^{-} > B r^{-} >$

$C l^{-} > P y > R N H_{2} \tilde{} N H_{3} > O H^{-} > H_{2} O]$
