What Is R in Functional Groups?
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. The symbol X denotes a halide such as F, Br, Cl or I.

.

Furthermore, what does the R stand for in a functional group?

R means “Radical Group” meaning any group in which a carbon or hydrogen atom is attached to the rest of the molecule. It substantially indicates an organic chain deprieved of its functional group.

Also, what is the R in hydroxyl? A hydroxyl group is composed of one hydrogen atom bonded to one oxygen atom. The R in the structural formula stands for the carbon backbone of the organic molecule to which the hydroxyl attaches.

One may also ask, is functional group same as R group?

The R-group concept is flexible. All three of these group are also functional groups. Quoting Wikipedia, "functional groups are specific groups (moieties) of atoms or bonds within molecules that are responsible for the characteristic chemical reactions of those molecules.

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−.
