Some dyes undergo this process in order to become colourful.
What is oxidation?
A bond formed by two p orbitals joining at the sides.
What is a pi bond?
These dyes come from plants or vegetables.
What are natural dyes?
A bond formed by two p orbitals joining head on.
What is a sigma bond?
These dyes are the same end product, but usually have to undergo more chemical changes.
What are synthetic dyes?
A conjugated system is made of these, which rapidly flip.
What are alternating double and single bonds?
This process converts an attached glucose into oxygen.
What is fermentation (in a base)?
The overlap of one p orbital across an intervening sigma bond.
What is conjugation?
In the case of indigo, this process bonds two compounds together to finally produce a colourful dye.
