Amines - amides - amino acids - polymers Flashcards
If one or more of the Hydrogens on Ammonia (NH3) is replaced with an organic group, you get a ______?
Amine ✨
Amines are organic derivatives of…….?
Ammonia
Small amines dissolve in water to form a solution that is acidic or alkaline??
Alkaline solution
Small amines in water are soluble or insoluble?
Soluble - the amine group can form hydrogen bonds with the water molecule ✨💧
Amines react with acids to form….?
Salts ✨✨
Amines act as a base because they can accept a proton - there’s a lone pair of e-s on the N atom and they form a dative covalent bond with an H+ ion 💘
Amides are derivatives of…….?
Carboxylic acids 🎉
Amides have the functional group???
-CONH2 😏
The carbonyl group in amiDes…….?
The carbonyl group pulls e-s away from the rest of the group ……. Making amides behave differently to amines ✨✨✨
Ammonia and amines can be acylated to form….
Amides!!! 💕
Acylation is when….?
Acylation is when an acyl group is substituted for a H atom.
Amides and amines (both contain the functional group -NH2 )what’s their difference between them??
Amides - straight chain
Amines - arene attached
Aromatic amines are used to make….?
Azo dyes
What is the azo functional group in azo dyes?
-N=N-
What makes azo dyes so stable??
Having 2 aromatic groups creates a v.stable molecule
⭐️⭐️⭐️
The azo group becomes part of the delocalised electron system
What causes the colours of azo dyes? And what makes different colours?
Different colours of an azo dye are made by combining different phenols and amines!
⭐️⭐️⭐️
The colours are the result of light absorption by the delocalised electron system.
