Find the number of ligands which are neutral & bidentate ligands among the following -
(a) en (b) bn (c) tn (d) pn
(e) dimethylglyoximato (f) ox
(g) acac (acetylacetanato)
(h) ethylenediaminetetraacetato
Options:
Answer:
Solution:
We need to identify the ligands that are both neutral and bidentate.
(a) en (ethylenediamine): Neutral, bidentate.
(b) bn (1,2-diaminopropane or propylenediamine): Neutral, bidentate.
(c) tn (1,3-diaminopropane or trimethylenediamine): Neutral, bidentate.
(d) pn (propylenediamine): Same as bn, Neutral, bidentate.
(e) dimethylglyoximato (dmg⁻): Anionic, bidentate.
(f) ox (oxalato, C₂O₄²⁻): Anionic, bidentate.
(g) acac (acetylacetonato, CH₃COCHCOCH₃⁻): Anionic, bidentate.
(h) ethylenediaminetetraacetato (EDTA⁴⁻): Anionic, hexadentate.
The neutral and bidentate ligands are en, bn, tn, and pn. There are 4 such ligands.
The final answer is .
