Is amine A NH3 or NH2?
Amines are organic derivatives of ammonia, NH3, in which one or more of the three H’s is replaced by a carbon group. Amines are classified as primary (1°), secondary (2°), or tertiary (3°), depending on how many carbon groups are connected to the nitrogen atom.
What are the types of amine?
Types of Amines
- Primary Amines ( 1 0 Amines) Primary amines created when an alkyl or aromatic group substitutes one of three hydrogen atoms in ammonia.
- Secondary Amines (2 0 Amines)
- Tertiary Amine (3 0 Amines)
- Quaternary Amines ( 4 0 Amines)
How do you write an amine?
Amines are named by naming the alkyl groups attached to the nitrogen atom, followed by the suffix -amine.
What is the formula for amide?
chain are linked together by amide groups. Amide groups have the general chemical formula CO-NH. They may be produced by the interaction of an amine (NH2) group and a carboxyl (CO2H) group, or they may be formed by the polymerization of amino acids or amino-acid derivatives (whose molecules contain both…
What functional group is NH2?
amines
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.
How basic is NH2?
NH2- Acid or Base NH2- is a strong base because it is unstable with its negative charge in a solution so that it wants to take the edge off with a negative charge by accepting a proton and acting as a base.
Which is 3 degree amine?
Tertiary (3°) amines—In tertiary amines, nitrogen has three organic substituents. Examples include trimethylamine, which has a distinctively fishy smell, and EDTA.
How many amines are there?
An amine is classified as a molecule that has an R group, meaning your carbon chain attached to a nitrogen. There are three major classes of amines. When you have an NH2 bound to a single R group, that’s a primary amine. When you have an NH bound to two R groups, represented as R and R prime, that’s a secondary amine.
What is the formula of aniline?
C6H5NH2
Aniline/Formula
Aniline, also known as aminobenzene or phenylamine, has 6 carbon (C) atoms, 7 hydrogen (H) atoms, and 1 nitrogen (N) atom in its chemical formula of C6H7N or C6H5NH2.

What is the chemical formula of amine?
Amine molecules have the general formula of R3-xNHx where R is a hydrocarbon group and 0 < x < 3. Put another way, amines are derivatives of ammonia, NH3, in which one or more hydrogen atoms have been replaced by hydrocarbon groups. Specific examples of amines are shown in the next section.
Which is the formula for the functional group in an amine?
Key Concepts Amines contain the -NH2 functional group which is known as the amine group (amino group(1)). Amines can be classified as : ⚛ primary (1o) : general formula R-NH2. ⚛ secondary (2o) : general formula R-NH-R’
What is the general formula for a secondary amine?
A secondary (2º) amine is an amine that has the following general structural formula. R1, R2 = alkyl and/or aryl. eg: The NH group in a secondary amine molecule is called the secondary amine group. See also primary amine and tertiary amine.
What is the structural formula for amine?
A primary (1º) amine is an amine that has the following general structural formula. R= alkyl, aryl. eg: The NH2 group in a primary amine molecule is called the primary amine group.
