Molecular vs Ionic Compound Nomenclature

***Disregard "old method" of naming ionic compounds that contain multivalent transition metals on this chart, and DO NOT CAPITALIZE LIKE THEY DID!***

Here are some Molecular Compounds, Ionic Compounds, Acids and bases to write their IUPAC name (or classical name if an acid) or to write the formula for. Try them!

Before you name them, know what type you have first…

TiCl_{3 (s)}  IONIC                                                                                      

titanium (III) chloride

 dinitrogen triarsenide    MOLECULAR                            

 N₂As₃                                    

CO _(g)   MOLECULAR                                                                                      

carbon monoxide                                      

beryllium nitrite IONIC                                                                           

Be(NO₃)_{2 (s)}        You could also put _(aq) as all nitrates are highly soluble          

CBr₄    MOLECULAR                                                                           

carbon tetrabromide           

HI _(aq)    ACID

aqueous hydrogen iodide or hydroiodic acid

(NH₄)₂SO_{3 (aq)} IONIC                                                         

aqueous ammonium sulphite   (ammonium sulphite in solution)               

hypochlorous acid  ACID

 (aqueous  hygrogen hypochlorite = “ous acid”) = HClO _(aq)  

Ca(OH)_{2  (s)}  IONIC (BASE)                                                          

calcium hydroxide (it is a base but calcium is only slightly soluble with hydroxide ions, therefore we use (s) and not (aq).

             

platinum (IV) carbonate   IONIC

Pt (CO₃)_{2  (s)}  platinum is insoluble with carbonate ions so we use (s)

Si₂F₆    MOLECULAR                                                                         

disilicon hexafluoride                                 

 H₃BO_{3 (aq)}    ACID                                                         

aqueous hydrogen borate or boric acid
