Lewis Super Acids

About Lewis Super Acids:

• Lewis super-acids are derived from Lewis acids, named after the chemist, G N Lewis.
• Lewis superacids are used as catalysts in chemistry to accelerate reactions.
• These are compounds that add electron pairs and can be used to break strong chemical bonds and speed up reactions.
• These are highly reactive reagents, thus difficult to produce and use.
• It enables non-biodegradable fluorinated hydrocarbons (similar to Teflon) to be converted back into sustainable chemicals.
• It can even convert climate-damaging greenhouse gases, such as sulphur hexafluoride into sustainable ones.

What are Lewis Acid and Base?

• Lewis Acid: It is an  electron-pair acceptor such as a Hydrogen ion (H+)
• Lewis Base: It is an electron-pair donor such as the hydroxide (OH-) ion.

Q1) What are the properties of acids ?

Acids have a sour taste, corrosive,change the color of certain vegetable dyes, such as litmus, from blue to red.
