Amines

Learning about the properties and reactions of amines, including basicity and nucleophilicity.

What are amines?

"In chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair."

What is the chemical composition of amines compared to ammonia?

"Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group."

What are alkylamines and arylamines?

"Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group. These may respectively be called alkylamines and arylamines."

What are examples of important amines?

"Important amines include amino acids, biogenic amines, trimethylamine, and aniline."

How are inorganic derivatives of ammonia classified?

"Inorganic derivatives of ammonia are also called amines, such as monochloramine (NClH2)."

What is the name for the substituent -NH2?

"The substituent −NH2 is called an amino group."

What is the classification for compounds with a nitrogen atom attached to a carbonyl group?

"Compounds with a nitrogen atom attached to a carbonyl group, thus having the structure R−CO−NR′R″, are called amides."

How do amines differ from amides?

"Compounds with a nitrogen atom attached to a carbonyl group [...] have different chemical properties from amines."

What is the definition of amines in the UK?

"In chemistry, amines (UK also ) are compounds and functional groups that contain a basic nitrogen atom with a lone pair."

What are the two types of substituents that can be attached to one nitrogen atom in amines?

"Amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines."

What are some examples of amines that are common in biological systems?

"Important amines include amino acids, biogenic amines..."

Give an example of an inorganic derivative of ammonia that is classified as an amine.

"Inorganic derivatives of ammonia are also called amines, such as monochloramine (NClH2)."

How are amines different from ammonium salts?

"Amines are formally derivatives of ammonia, wherein one or more hydrogen atoms have been replaced... This differentiates them from ammonium salts."

How do amines and amides compare in terms of chemical properties?

"Compounds with a nitrogen atom attached to a carbonyl group have different chemical properties from amines."

What are the general characteristics of amines?

"Amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair."

What is the role of alkylamines in amines?

"These [substituents] may respectively be called alkylamines..."

What type of functional group is present in amines?

"Amines are formally derivatives of ammonia... that contain a basic nitrogen atom with a lone pair."

Can you provide an example of an arylamine?

"These [substituents] may respectively be called... arylamines."

How are amines related to amino acids?

"Important amines include amino acids..."

Are amines similar or different from amines with alkyl and aryl groups attached to one nitrogen atom?

"Amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines."
