Alkyl compounds are organic molecules derived from alkanes, which are saturated hydrocarbons. They consist of carbon and hydrogen atoms, with the general formula CₙH₂ₙ₊₂. Alkyl groups are formed when one hydrogen atom is removed from an alkane, resulting in a structure that can bond with other atoms or groups. These compounds play a significant role in organic chemistry and are often used as building blocks in the synthesis of more complex molecules. Common examples include methyl, ethyl, and propyl groups, which are frequently found in various chemical reactions and industrial applications.
