Key Facts & Summary for the Structure and Properties of Amines:
- An amine is an organic compounds or a functional group that contains a basic nitrogen atom.
- The nitrogen in an amine has a lone pair (a pair of valence electrons that are not shared with another atom).
- The polar nature of the N-H bond (due to the electronegativity difference of the two atoms) results in the formation of hydrogen bonds .
What are the functional groups of nitrogen?
Nitrogen-Containing Functional Groups Amines RNH 2 primary (1°) R 2NH secondary (2°) R 3N tertiary (3°) CH 3CH 2NH 2 ethylamine PhCH 2NH 2 benzylamine NH 2 aniline N diisopropylethylamine Hunig's base Amides R'(C=O)NH
What group contains nitrogen?
They are normally prepared by three methods:
- Replacing labile ligands such as H 2 O, H −, or CO directly by nitrogen: these are often reversible reactions that proceed at mild conditions.
- Reducing metal complexes in the presence of a suitable coligand in excess under nitrogen gas. ...
- Converting a ligand with N–N bonds, such as hydrazine or azide, directly into a dinitrogen ligand.
How to identify functional groups?
Analysis of Functional Groups using Infrared (IR) Spectroscopy INTRODUCTION Infrared spectroscopy is a technique that can be used to identify which functional groups are present in a compound. The bonds in a molecule can stretch, bend and wag, similar to balls that are attached to springs. Here are some different types of bond movements.
What are the 7 functional groups in chemistry?
Key Takeaways: Functional Groups
- In organic chemistry, a functional group is a set of atoms within molecules that function together to react in predictable ways.
- Functional groups undergo the same chemical reactions no matter how large or small the molecule is.
- Covalent bonds link the atoms within functional groups and connect them to the rest of the molecule.
Which functional group contains a nitrogen atom quizlet?
The functional group of an amine is an amino group, a nitrogen atom bonded to one, two, or three carbon atom(s) by single bonds. In a primary (1°) amine, nitrogen is bonded to one carbon atom.
What compound contains nitrogen?
Nitrogen forms many organic compounds including amines, amino acids, amino alcohols, amides and lactams, nitro compounds, imines, nitriles, diazonium salts, hydrazides, carbazides, oximes, and heterocyclic compounds such as imidazole, triazole, and tetrazole.
What functional group contains nitrogen and hydrogen?
The amide functional group has an nitrogen atom attached to a carbonyl carbon atom. If the two remaining bonds on the nitrogen atom are attached to hydrogen atoms, the compound is a simple amide.
What functional group has NH?

Does aldehyde contain nitrogen?
Answer and Explanation: Amines are the class of organic compounds that contain nitrogen. Aldehydes contain RCHO R C H O functional group, alcohols contain R−OH R − O H ...
Which functional group contains nitrogen and oxygen?
Amines are composed of a nitrogen atom bonded to some combination of carbons and hydrogens. Amines are weak bases commonly used in pharmaceuticals. Carbonyl is composed of a carbon atom double bonded with an oxygen atom, and is a common structural component of many other organic molecules.
Does amine contain nitrogen?
In organic chemistry, amines (/əˈmiːn, ˈæmiːn/, UK also /ˈeɪmiːn/) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.
Do ethers contain nitrogen?
Amines contain singly-bonded nitrogen atoms; the nitrogen may be connected to either carbon or hydrogen. Ethers contain singly-bonded oxygen atoms connected only to carbons.
Which funcional group contains nitrogen?
The funcional group that contain nitrogen is amino group.
What is an amino group?
An amino group (−NH2) is a functional group that is comprised of a nitrogen atom attached by single bonds to hydrogen atoms. Nitrogen is the principal element of the amino group. Amino groups are very important for being an essential functional group for amino acids, the individual elements that form all the proteins.
Which functional group contains oxygen?
Another functional group that contains the oxygen atom in single bonds is ether. In ether, the O atom connects with two carbon-containing R groups through two C-O σ bonds. For compounds with ether as the only functional group, it is usually named with the common name “alkyl alkyl ether”. When the two alkyl groups are the same, they can be combined as “dialkyl”.
What is functional group?
Functional groups are the most reactive parts in organic compounds, and determine the major properties of compounds. The summary of common functional groups is included in Table 2.2. Knowing the functional groups well is one of the fundamental skills required for this course. It is required in order for students to quickly identify and name the functional groups included in molecules, as well as to understand, interpret and draw the specific structure of each functional group clearly. The IUPAC naming of compounds containing a couple of functional groups is required as well.
What is the name of the group of halogens?
When a halogen is connected with carbon, the group is called alkyl halide (or haloalkane). The halide can be categorized as a primary (1°), secondary (2°) or tertiary (3°) halide, depending on what category the carbon connected with the halogen is in. Alcohol is a functional group that you probably are familiar with.
What are the last four functional groups?
The last four functional groups are related in terms of structures and chemical properties. When an OH group is connected with C=O, the whole COOH is called a carboxylic acid functional group. The other three, ester , anhydride and amide, are all derivatives of carboxylic acid, meaning they can be prepared with carboxylic acid as ...
What is a benzene ring?
Benzene rings (C 6 H 6) are a special type of hydrocarbon. Historically, because of the special aroma (sweet smelling) that benzene and its derivatives release, they are called aromatic compounds. The structure of benzene can be represented as three C=C double bonds alternate with single bonds, however, the actual structure of benzene has nothing to do with alkenes. Detailed discussions on the structure of benzene, which is a big conjugation system, and the chemistry definitions of aromatic/aromaticity will be a topic of Organic Chemistry II. Benzene rings can be shown with any of the following structure drawings.
What is the name of the organic derivative of ammonia?
Amine is the organic derivative of ammonia, NH 3. When the hydrogen atom (s) in NH 3 is replaced with R groups, it produces amine. The amine can be primary (1°), secondary (2°) or tertiary (3°) depending on how many R groups are connected with nitrogen. The amines can also be named with common names.
Is ether cyclic or nitrile?
Ether can be in cyclic structure as well. It may not be that intuitive to recognize the following structure as ether, and labelling the carbon atom will be helpful for identification. Figure 2.3g Cyclic ether examples. Both nitrile and nitro groups contain nitrogen atom, and it might be easy to get them mixed up.
