Naming

Postby elliekauffman1I » Sun Dec 03, 2017 2:57 pm

When naming structures, there are times when you must use different prefixes such as bis. When do we use these instead of the regular ones?

You would use prefixes such as bis and tris for molecules that are bidentate or ploydentate.

If the ligand already has a greek prefix, or is a polydentate (is able to attach at more than one binding site), you use the "special" type of prefixes (bis for 2, tris for 3, tetrakis for 4)

Ligands such as ethylenediamine and diethylenediamine would use these prefixes rather than the normal ones.

You use "bis-", "tris-" etc when the ligand already has a prefix such as "di-" or "tri-"

Could someone help me name and draw the Lewis structure for the test problem [HgF2(OH2)2]+
