  1. More Nomenclature this time…acids and molecular compounds

  2. Acids • will always have H+ as the cation • names are determined by the name of the anion present • will be in aqueous phase, (aq)

  3. Acids with “ide” anions • drop the suffix “ide” to leave the root word • add “hydro” as a prefix and “ic” as a suffix • end with “acid” as a separate word

  4. Acids with “ide” anions • HCl • anion is chloride • drop “ide” and you’re left with “chlor”

  5. Acids with “ide” anions • add “hydro” as a prefix of “chlor” • add “ic” as a suffix of “chlor” • add “acid” as a separate word • Shazam! “hydrochloric acid”

  6. Acids with “ite” anions • drop the suffix “ite” to leave the root word • add “ous” as a suffix • end with “acid” as a separate word

  7. Acids with “ite” anions • H2SO3 • anion is sulfite • drop “ite” and you’re left with “sulf”…S and P are special cases…

  8. Acids with “ite” anions • change what you’re left with to “sulfur” (or in P’s case, to “phosphor”) • add “ous” as a suffix • add “acid” as a separate word

  9. Acids with “ite” anions • Ooh, Ah…it’s “sulfurous acid”

  10. Acids with “ate” anions • drop the suffix “ate” to leave the root word • add “ic” as a suffix • end with “acid” as a separate word

  11. Acids with “ate” anions • H2SO4 • anion is sulfate • drop “ate” and you’re left with “sulf”…again, S and P are special cases…

  12. Acids with “ate” anions • change what you’re left with to “sulfur” (or in P’s case, to “phosphor”) • add “ic” as a suffix • add “acid” as a separate word

  13. Acids with “ate” anions • Wacka, Wacka!…it’s “sulfuric acid”

  14. Molecular Cpds • will always be made of nonmetals (consider B and Ga to have nonmetallic properties) • use those fun prefixes we use for hydrates • end in “ide”

  15. Molecular Prefixes • mono • di • tri • tetra • penta • hexa • hepta • octa • nona • deca

  16. Molecular Names • use prefixes on first element if there is a subscript • always use prefixes on second element

  17. Molecular Names • CO • It’s molecular because there is no metal in it. • There is only one carbon, and it is the first element in the cpd.

  18. Molecular Names • So, it does not get a prefix. • There is only one oxygen; so, its prefix is “mono” (which will be abbreviated to “mon” because O begins with an “o”)

  19. Molecular Names • add “ide” as a suffix to the root of the last element name • So, when we put them together… • carbon monoxide is the name

  20. Molecular Names • N2O4 • two nitrogen atoms • four oxygen atoms • hmmm….

  21. Molecular Names • dinitrogen tetroxide!!!!

  22. A Bit o’ Practice • HClO3(aq) • CS2 • PF3 • HCN (aq) • NO2 • H3PO3(aq) • BI3 • HIO4(aq) • P2O5 • H2C2O4(aq)

  23. A Bit o’ Practice • oxygen difluoride • hydrophosphoric acid • carbon tetrachloride • chlorous acid • chromic acid
