This is because different atoms combine in different ratios and . 2. For compounds that consist of one or more ions, the cation is named first, followed by the anion (as for simple ionic compounds), regardless of which ion is complex. Nomenclature of coordination compounds follows different rules which are as follows. 2.

Chemistry Notes XII: Coordination compounds.
Na [PtCl 3(NH 3)] Sodium . The name is started with a small letter and the complex part is written as one word.
Coordination entity: It constitutes a central metal atom/ion bonded to a fixed number of ligands with coordinate bonds. Rules for naming ambidentate ligand - definition. This article provides the revision notes of the Coordination Compounds chapter of Class 12 Chemistry for the students so that they can give a quick glance of the chapter during exams.
For compounds that consist of one or more ions, the cation is named first, followed by the anion (as for simple ionic compounds), regardless of which ion is complex. You will learn more about coordination compounds in the lab lectures of experiment 4 in this course. The name is started with a small letter and complex part is written as one word. Nomenclature of coordination compounds. If the coordination compound is accompanied by a counter ion, the cationic entity must be written before the anionic entity.
⇒ Also Read: Nomenclature of Organic Compounds. For example: NaCl is ionic and written as sodium chloride that is in name first part is cationic and other is anionic. Hence this topic can be used to obtain easy marks . Class 12 Chemistry Coordination Compounds. Name ligands . Ligands are named first and central atom last. uncharged) in which at least one ion is present as a complex. ⇒ Also Read: Nomenclature of Organic Compounds.
Some examples of the nomenclature of coordination compounds can be found below. Order of naming ions: The positive ion (cation) whether simple or complex, is named first followed by the negative ion (anion). Coordination Compounds Class 12 Notes. Facebook.

Tridentate ligands: Ligands which have three donor atoms per ligand, e . Order of naming ligands - definition Ligands are listed in the following order: negative ions, neutral molecules, and positive ions. There are exercises that are given at the end of each chapter. Questions appearing in the exam are direct. e.g., Potassium ferrocyanide, K 4 [Fe(CN) 6]. Each year, there are questions of 4-6 marks asked from this chapter. Unidentate ligands: Ligands with only one donor atom, e.g. A complex is a substance in which a metal atom or ion is associated with a group of neutral molecules or anions called ligands. 2. Is . For example, K[PtCl 3 (C 2 H 4)] was called Zeise's salt and [Pt(NH 3 . For coordination compounds that are ionic (i.e., the coordination complex is either an anion or anion of an ionic substance), the cation is named first and separated by a space from the anion, as is the case for all ionic compounds. Complex ions are named with their ligands in alphabetical order (ignoring any numerical prefixes). are coordinate compounds of Mg, Fe, and Co respectively.
