What is the name of the alkane with the chemical formula CH4?

An alkane is a saturated hydrocarbon. This means that an alkane only contains carbon and hydrogen atoms that are joined together by single covalent bonds. The alkane in the question is CH4 which has this displayed formula in which one carbon atom is joined to four hydrogen atoms with single covalent bonds. To answer the question, we need to determine the name of this alkane. So let’s take a look at how to name a simple straight-chain alkane, in which all of the carbon atoms in the structure are bonded in one continuous chain.

We can name these alkanes by naming the longest continuous chain of carbon atoms by adding the suffix A-N-E to a root word that indicates the number of carbon atoms. The first 10 root or base terms are shown in the table. Since the alkane in the question only contains one carbon atom, we name this compound using the root meth- followed by the suffix -ane. Therefore, the name of the alkane with the chemical formula CH4 is methane.
