... nomenclature coordination-compounds organometallic-compounds. It can bind through two nitrogen and four oxygen atoms to a central metal ion. Each question has four choices (a), (b), (c) and (d), out of which ONLY ONE is correct. •  If the name of the ligand itself has such a prefix, alternatives like bis-, tris-, etc., are used. acac = Acetylacetonato, chelating .uninegative, bipy = 2 , 2 ' bipyridine , bidentate, neutral, DMG = Dimethylgloxol, bidentate and neutral. The systematic approach taken for the nomenclature of organic compounds as per the recommendation of the International Union of Pure and Applied Chemistry (often abbreviated to IUPAC) is known as IUPAC nomenclature of organic compounds. Direction (Q. Nos. 5. If the complex is anionic, name of the metals ends with ‘ate’. Non-ionic or neutral complexes are given a one word name. When we see that there are multiple types of ligands present in any coordination compound, we name the ligands in alphabetic order after by the name of central metal atom/ion. The IUPAC name of NaBH4 is sodium tetrahydridoborate. The number of complexes in which iUPAC names contain metal name ending with ‘ate’, K[Co(EDTA)], [Pt(NH3)4]Br4, [Co(NO2)6]3-, [FeF6]3-, [Pt(en)CI2Br2] [Pt(en2)]2+, K[Co(EDTA) [Pt(py)4] [PtCI4]. 1. 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. Class 12 th NCERT is best advised to cover up the chapter along with previous year question paper..

Select the correct answer from the codes given below. 2. 18 and 19) Choices for the correct combination of elements from Column I and Column II are given as options (a), (b), (c) and (d), out of which one is correct. This chemistry video tutorial provides a basic introduction into naming coordination compounds. Write down the molecular formulae of the following co-ordination compounds. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons More complicated coordination compounds are composed of an atom or ion (usually a metal) and a surrounding array of bound molecules or anions, known as ligands. This tag should be used for questions about the naming of compounds and elements, usually using systematic names according to IUPAC recommendations, but also using retained traditional names. tetrachloronickel (II) tetramminenickel (II), tetramminenickel (II) tetrachloronickel (II), tetramminenickel (II) tetrachloronickelate (II), tetrachloronickel (II) tetramminenickelate (0). K [Pt(NH3)CI5] = potassiumamminepentachloridoplatinate (IV), K3[Cr(C2O4)3] = tripotassium trioxalatochromate(lll), Na2[Ni(EDTA)] = sodium ethylenediaminetetraacetatonickel(ll). Statement II : IUPAC name of the complex [Ni(dmg)2] is bis (dimethylglyoximato) nickel (III). The number of ligands that attach to a metal depends on whether the ligand is monodentate or polydentate. ​ When the coordination centre is bound to more than one ligand, the names of the ligands are written in an alphabetical order which is not affected by the numerical prefixes that must be applied to the ligands. 8. For example, Chloride → Chlorido, Nitrate → Nitrito 2. Ans. Naming of the Geometrical isomers. The correct name of ligand in IUPAC name are thiosulphate and cyclopentadienyl [(C5H5)-].
