what is an alkyl group?
An alkyl group is a group of atoms formed by removing one hydrogen atom from an alkane. It is represented by the general formula CₙH₂ₙ₊₁ and is often denoted by the symbol R in organic chemistry.
Common Alkyl Groups:
| Alkane | Alkyl Group | Formula |
|---|---|---|
| Methane | Methyl | CH₃– |
| Ethane | Ethyl | C₂H₅– |
| Propane | Propyl | C₃H₇– |
| Butane | Butyl | C₄H₉– |
Example:
When one hydrogen atom is removed from methane (CH₄), the methyl group (CH₃–) is formed.
In simple terms: An alkyl group is a part of an alkane molecule that can attach to other atoms or groups to form organic compounds.
