The minimum number of unshared valence electron pairs in the ligands of a coordination compound is one.
Answer: Option A
Step-by-step explanation:
The metal and ligand are joined by a covalent bond, comprising of two electrons shared between them. the two electrons are given by the ligand itself. In coordination science, a ligand refers an ion or a molecule (functional gathering) that ties to the central metal particle to frame a coordination complex. Practically every molecule and each ion can fill in as ligand for (or the coordinate to) metals.
Denticity denotes the occasions a ligand bond to metal through contributor atoms. Numerous ligands are equipped for restricting metal ions through different destinations, generally in light of the fact that the ligands have solitary matches on more than one particle.
Metal atom or ion, as a rule, cling to two, four or six ligands. These are orchestrated with geometric symmetry surrounding the central metal molecule. The metal collectively with its ligands is known as a coordination compound. On the off chance that the structure has a general electrical charge, it is known as a complexion.
