Question

give the name or formula. for parts 1 and 2, enter your answer as all lower case with appropriate spacing. for parts 3 and 4 use capital letters where appropriate but don't worry about sub or superscripting. what is the systematic name of na3[alf6]? what is the systematic name of [co(en)2cl2]no3? what is the formula of diamminedichloroplatinum(iv) chloride? what is the formula of hexaamminecobalt(iii) tetrachloroferrate(iii)?

Answer 1

The systematic names and formulas are sodium hexafluoroaluminate(III) for Na3[AlF6], dichloridobis(ethylenediamine)cobalt(III) nitrate for [Co(en)2Cl2]NO3, Pt(NH3)2Cl4 for diamminedichloroplatinum(IV) chloride, and [Co(NH3)6][FeCl4]3 for hexaamminecobalt(III) tetrachloroferrate(III).

Step-by-step explanation:

The systematic name of Na3[AlF6] is sodium hexafluoroaluminate(III). The aluminum ion has an oxidation state of +3, as indicated by the Roman numeral III, and is surrounded by six fluoride ions, hence 'hexafluoro'.

The systematic name of [Co(en)2Cl2]NO3 is dichloridobis(ethylenediamine)cobalt(III) nitrate, where 'Co' stands for cobalt with a +3 oxidation state, 'en' stands for ethylenediamine, a bidentate ligand, and the compound has two chloride ions and a nitrate counter ion.

The formula of diamminedichloroplatinum(IV) chloride is Pt(NH3)2Cl4. 'Diammine' indicates that there are two ammine (NH3) ligands, 'dichloro' indicates two chloride ligands directly bonded to the platinum ion, and the additional 'chloride' indicates there is a counter ion of chloride.

Last, the formula for hexaamminecobalt(III) tetrachloroferrate(III) is [Co(NH3)6][FeCl4]3. This indicates a cobalt(III) center surrounded by six ammonia ligands and three tetrachloride ferrate(III) anions.
