What is the R in functional groups?
The letter R is used in molecular structures to represent the “Rest of the molecule”. It consists of a group of carbon and hydrogen atoms of any size. It is used as an abbreviation since a group of carbon and hydrogen atoms does not affect the functionality of the compound.
What is NH in organic chemistry?
In organic chemistry, amines (/əˈmiːn, ˈæmiːn/, UK also /ˈeɪmiːn/) are compounds and functional groups that contain a basic nitrogen atom with a lone pair. The substituent -NH2 is called an amino group.
What is HN chemistry?
Hydrazoic acid, also known as hydrogen azide or azoimide, is a compound with the chemical formula HN3. It is a colorless, volatile, and explosive liquid at room temperature and pressure. It is a compound of nitrogen and hydrogen, and is therefore a pnictogen hydride. It was first isolated in 1890 by Theodor Curtius.
What is NH in solution?
Ammonia. Standard Solution Ammonia, 5.2 mg/l NH = 4.0 mg/l N.
What is an R group in chemistry?
R group: An abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule. Sometimes used more loosely, to include other elements such as halogens, oxygen, or nitrogen.
What is R in a molecule?
R group: An abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule. R is an abbreviation for radical, when the term radical applied to a portion of a complete molecule (not necessarily a free radical), such as a methyl group.
What is r in hydrocarbon?
Functional groups are groups of atoms found within molecules that are involved in the chemical reactions characteristic of those molecules. The symbol R and R’ refer to an attached hydrogen or hydrocarbon side chain or sometimes to any group of atoms.
What is a NH2 group called?
The amine group is located by the position number. Groups that are attached to the nitrogen atom are located using “N” as the position number. More complex primary amines are named with —NH2 as the amino substituent.
Do amides smell bad?
Most amides are colorless and odorless, and the lighter ones are soluble in water. Because they are polar molecules, amides have comparatively high boiling points and melting points. Amides are synthesized from carboxylic acids and NH 3 or amines.
Which is the nitrogen containing group in RNH?
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

Where does the NH occur in an amine molecule?
The amine functional group (NH) occurs between 2 carbon atoms. One hydrogen atom in the ammonia molecule has been replaced by a methyl, CH 3, group and another hydrogen atom in the same ammonia molecule has been replaced by a different methyl, CH 3, group.
Who are the professors in the Department of Chemistry?
