Identify monodentate ligand from the following.

A. Cyanide ion

B. Ethylenediamine

C. Oxalate ion

D. Ethylendiaminetetraacetate

Correct Option is (A)

Ligand	Type of ligand
${CN}^{-}$	Monodentate
Ethylenediamine	Bidentate
Oxalate ion	Bidentate
Ethylendiaminetetraacetate	Hexadentate

7. ⇒ (MHT CET 2023 9th May Evening Shift )

Which from the following coordinate complexes contains anionic and neutral ligands in it?

A. Potassium trioxalatoaluminate(III)

B. Hexacyanoferrate (II)

C. Pentaamminecarbonatocobalt (III) chloride

D. Tetraamminecopper(II) ion

Correct Option is (C)

Pentaamminecarbonatocobalt(III) chloride: $[Co {({NH}_{3})}_{5} ({CO}_{3})] Cl$

It contains anionic ligand $({CO}_{3}^{2 -})$ and neutral ligand $({NH}_{3})$ .

${NH}_{3}$ (named as ammine) is a neutral ligand. Both (C) and (D) contain ${NH}_{3}$ ligand. However, (D) contains only ${NH}_{3}$ . Hence, option (C) should be valid.

8. ⇒ (MHT CET 2023 9th May Morning Shift )

Identify neutral ligand from following

A. Ammine

B. Nitrato

C. Cyano

D. Chloro

Correct Option is (A)

The neutral ligand from the options provided is :

Option A

Ammine

An ammine in coordination chemistry refers to an ammonia molecule acting as a ligand, attached to the central metal atom/ion through a lone pair of electrons. It is neutral because the ammonia molecule itself does not carry any net charge.

9. ⇒ (MHT CET 2021 21th September Morning Shift )

Which among the following is NOT a neutral ligand?

A. Thiocyanate

B. Ammine

C. Aqua

D. Carbon monoxide

Correct Option is (A)

Thiocyanate (SCN $^{-}$ ) is a neutral ligand.

10. ⇒ (MHT CET 2021 20th September Morning Shift )

Identify highest field strength ligand from following.

A. H $_{2}$ O

B. EDTA

C. en

D. S $^{-}$ $^{-}$

Correct Option is (C)

Ligands strength $\Rightarrow$ S $^{2 -}$ < H $_{2}$ O < EDTA < en
