Organic Molecules With Sulfur and Phosphorus

organic chemistry - structural model for penicillin vBecause sulfur is in the same group as oxygen, it shares many characteristics with it. Many of the functional groups that oxygen can form, sulfur can form as well. Although, due to the ability to expand beyond the octet, sulfur can create some more complex functional groups involving up to six bonds. Some notable functional groups that involve sulfur are:

 

  • Thiols
  • Thioesters
  • Sulfoxides
  • Sulfonic Acids
  • Thiones
  • Thials

Phosphorus is also like nitrogen in how it can form some similar functional groups. In addition to this, like sulfur to oxygen, the ability to expand beyond the octet of electrons allows it to have more complicated functional groups involving more than four bonds. Some notable functional groups that involve phosphorus are:

  • Phosphines
  • Phosphates
  • Phosphonic Acids
  • Phosphodiesters
