What is an ester amide?

These poly(ester amides) are intrinsically biodegradable and synthesized from cyclic anhydride (e.g., succinic anhydride) and a diisopropanol amine. Hyperbranched poly(ester amides) are used as performance additive in many applications such as oil field chemicals, demulsifiers, drug carriers, paper coatings, etc.

Which functional groups are present in ester and amine?

In an ester, the hydrogen of a carboxylic acid group is replaced by an alkyl group. Amines are derivatives of ammonia that are weak bases due to the lone pair of electrons on the nitrogen atom.

What is the functional group of amines?

An amine is generally a functional group with a nitrogen atom having a lone pair. Amines resemble ammonia structurally where nitrogen can bond up to 3 hydrogen atoms. It is also characterized by various properties that are based on carbon connectivity.

What is nh2 group called?

amino group
The substituent –NH2 is called an amino group. Compounds with a nitrogen atom attached to a carbonyl group, thus having the structure R–CO–NR′R″, are called amides and have different chemical properties from amines.

What is amide structure?

Amides have a general structure in which a nitrogen atom is bonded to a carbonyl carbon atom. The functional group for an amide is as follows: In names for amides, the -ic acid of the common name or the -oic ending of the IUPAC for the corresponding carboxylic acid is replaced by -amide.

What is the functional group of ether and ester?

Esters have the functional group –COO. Ethers have the functional group –O- Esters do not have symmetrical structures due to the presence of the carbonyl group. Ethers can have a symmetrical structure if both alkyl groups on either side of the oxygen atom in an ether group are similar.

What is Ester formula?

Esters have the general formula RCOOR′, where R may be a hydrogen atom, an alkyl group, or an aryl group, and R′ may be an alkyl group or an aryl group but not a hydrogen atom. (If it were hydrogen atom, the compound would be a carboxylic acid.)

What is NH2 called in functional group?
