Question

Methylamine $[C{{H}_{3}}N{{H}_{2}}]$ is a bidentate ligand.
If true enter 1, else enter 0.

Answer 1

Hint: Ligands are molecules that are attached to the central metal atom in the coordination compound. In bidentate ligand, there are two sites for attaching to the central metal atom.

Complete step by step answer:
Coordination compounds are the compounds in which the central metal atom is linked to several ions or neutral molecules by coordinate bonds, i.e., by donation of lone pairs of electrons by these ions or neutral molecules to the central metal atoms.
The donor atoms, molecules, or anions that donate a pair of electrons to the metal atom or ions and form a coordinate bond with it are called ligands. The metal atom or ion to which these ligands are attached is called the central metal atom or ion.
The number of coordinating or ligating groups present in a ligand is called the denticity of that ligand.
Monodentate ligand has one donor atom, the bidentate ligand has 2 donor atoms, tridentate has 3 donor atoms, and so on.
For example, Ammonia ($N{{H}_{3}}$ ), water (${{H}_{2}}O$ ) are examples of the monodentate ligand.
Oxalate ion ($2CO{{O}^{-}}$ ): is a bidentate ligand because it has 2 oxygen donor atoms.
The structure of Oxalate ion is:

So, in Methylamine $[C{{H}_{3}}N{{H}_{2}}]$, has one donor atom, i.e., nitrogen. Hence, it is a monodentate ligand.
Hence, Methylamine $[C{{H}_{3}}N{{H}_{2}}]$ is a bidentate ligand is false.

Note: Ligands are classified as negative, positive, and neutral ligands. The negative ligand has a negative charge, the positive ligand has a positive charge and the neutral ligand has zero charges. Methylamine $[C{{H}_{3}}N{{H}_{2}}]$ is a neutral ligand.
