Give the order of chelating effect of following ligands.
(i) `C_(2)O_(4)^(2-)` (ii) EDTA (iii) dien

A

`iii gt ii gt i`

B

`i gt ii gt iii `

C

`ii gt iii gt i`

D

`igt iii gt ii `

Text Solution

Verified by Experts

The correct Answer is:
C
As number of donor atoms increases the number of bonds increases. So the chelating effect of ligands increase as oxalato, dien and EDTA has two, three and six donor atoms respectively.
