Thio
Thio - (from Greek theion 'sulfur') is a prefix used for chemical compounds in which oxygen has been replaced by sulfur . This is very often possible because sulfur has a very similar electron configuration to oxygen, recognizable by the fact that it is in the same main group in the periodic table as oxygen.
Examples
- Sulfuric acid → thiosulfuric acid , or sulfates → thiosulfates
- Cyanates → thiocyanates and isocyanates → isothiocyanates
- Dithiocarbamate , the basis of numerous pesticides
- Sodium Dithionite
- Alcohols → thiols or mercaptans
- Ether → thioether
- Carbonyl group → thiocarbonyl group
- Aldehyde → thioaldehyde
- Ketone → thioketone
- Carboxylic acid ester → thiolester , thionester or dithioester
- Amide → thioamide
- Ketenes → Thioketenes
- Phosgene → thiophosgene
