Poly-amines are more durable, poly-amides are more resistant to moisture.
Amines are produced when a hydrogen atom in ammonia has been replaced by an alkyl or aryl group. Examples of amines are biogenic amines, amino acids and aniline.
German's won the battle of amines
cyanide
because aromatic amines are stronger acid due to its being a secondary amine
Not necessarily. Amines contain nitrogen, but many do not contain oxygen.
Amines + Nitrates/Nitrites = carcinogenic nitrosamines
In gabriel synthesis on primary amines are formed. Secondary and tertiary amines are not formed this yields in pure rimary amine product. Hence Gabriel phthalimide synthesis is preferred for synthesising primary amines
in amines a unshared pare of electron is present over nitrogen which is responsible for its basic character.
Due to the absence of replaceable hydrogen atoms
Bcoz alipatic amines require very low temperature like about -25 degrees celsius...which is difficult to maintain.....thats y its not posible to form diazonium salt with aliphatic amines...where as for aromatic amines its posible as temperature range is 0 - 5 degres..
Gaseous amine possess a characteristic ammonia smell, while liquid amines have a distinctive "fishy" smell.
