NC4H9

NC4H9 is a chemical formula that represents a butyl group. A butyl group is a four-carbon alkyl radical derived from butane by the removal of one hydrogen atom. The formula indicates that the molecule contains four carbon atoms and nine hydrogen atoms. There are several structural isomers of butyl groups, including n-butyl, sec-butyl, isobutyl, and tert-butyl. The specific arrangement of these atoms determines the isomer and its properties. For instance, n-butyl has a linear chain of four carbons, while tert-butyl has a central carbon atom bonded to three other carbon atoms. These isomers can participate in various chemical reactions, forming ethers, esters, and other organic compounds. The term NC4H9 is often used in organic chemistry to denote a substituent group within a larger molecule, rather than a standalone compound. Its presence contributes to the overall physical and chemical characteristics of the molecule it is part of, such as solubility, boiling point, and reactivity.
