Article name

[edit]

Please discuss any concerns about the article name here. Vsmith (talk) 01:44, 7 April 2010 (UTC)[reply]

I have a problem with this name is because this chemical is an ionic compound not a molecular compound. The prefix "di" shouldn't be used to name ionic compound. Plus, the ion lead has multiple charges. The correct name should be "Lead(IV) Oxide" I use the roman numeral (IV) means that the lead ion has a +4 charge. --Flushing258 (talk) 03:05, 13 April 2010 (UTC)[reply]

A few points:
  • You have not given a reliable source that says PbO2 is ionic — it may seem obvious from school-level chemistry, where you think of most inorganic compounds as ionic, i.e. [Pb4+][O2−]2, but this a gross simplification. See Ionic bond: "Pure ionic bonding is not known to exist. All ionic compounds have a degree of covalent bonding." I will try and find a reliable source that explicitly discusses the degree of separation of charge in PbO2, but in general I believe the greater the formal charge on the ion (i.e. especially pronounced with a formal tetracation like Pb4+), the less likely it is to find fully ionic bonding. The energy required to ionise Pb to Pb4+ and 2O to 2O2− probably cannot be compensated for by the energy gained from forming Pb4+···O2− ionic bonds. Structure determinations:

  • You have not given a reliable source to suggest that "lead dioxide" is an inappropriate name for an ionic compound.
  • Lead(IV) means Pb is in the +4 oxidation state, which is not exactly the same thing as saying lead has a +4 charge. "Lead(IV) oxide" would be an acceptable name for PbO2, but it is not necessarily preferable to "lead dioxide", and "lead dioxide" is certainly not wrong.
  • Only the first letter of article titles is capitalised, so it would be "Lead(IV) oxide", not Lead(IV) Oxide".
For these reasons, I oppose any move to Lead(IV) Oxide.

Anhydrous plumbic acid

[edit]

I've never heard this name used but I suppose it is analagous to Chromium trioxide and Chromic acid. Biscuittin (talk) 19:02, 23 November 2014 (UTC)[reply]
