Can an R be a hydrogen?
In organic chemistry, functional groups are specific groups of atoms within molecules arranged in a specific manner. The symbols R, R’, R” and R”’ usually denote a hydrocarbon chain or a hydrogen but can sometimes be any group of atoms.
Can an R-group be a single hydrogen?
An aldehyde is a carbonyl in which the carbon atom is bonded to at least one hydrogen atom. The other group attached to the carbonyl may be an R-group or a hydrogen atom.
What does R mean in chemistry?
Often when drawing organic structures, chemists find it convenient to use the letter ‘R’ to designate part of a molecule outside of the region of interest. ” R” represents the “Rest of the Molecule”.
How do you represent a hydrogen atom?
The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force….Hydrogen atom.

What is R and R in chemistry?
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 r in alkyl group?
In organic chemistry, an alkyl substituent is an alkane missing one hydrogen. Typically an alkyl is a part of a larger molecule. In structural formula, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula CH3−.
Are R groups hydrophobic or hydrophilic?
There are about 10 nonpolar amino acids with R-groups that are not stable when in contact with water. They are hydrophobic. About 5 amino acids have polar side chains, R-groups which do not ionize or become positively or negatively charged. These R-groups are neither strongly hydrophilic nor hydrophobic.
