- These are compounds that add electron pairs.
- These can be used to break strong chemical bonds and speed up reactions.
- These are highly reactive reagents, thus difficult to produce and use.
- Significance – It enables non-biodegradable fluorinated hydrocarbons (similar to Teflon) to be converted back into sustainable chemicals.
- It can possibly even convert climate-damaging greenhouse gases, such as sulphur hexafluoride into sustainable ones.
