Which name describes a three-carbon alkane? o pentane o methane o butane o propane o heptane

Propane

Explanation:

Hello,

IUPAC rules for organic chemistry nomenclature states that depending on the number of carbon atoms in the molecule we use standardized prefixes and suffixes. In particular, a three-carbon alkane is made up of three carbon single-bonded atoms, in such a way, the suitable prefix for three carbons is "prop". Now, as the statement is referring to an alkane, we use the suffix "ane" which stands for the presence of just single bonds among carbons. It means that the correct name of such alkane is propane whose structure is shown on the attached picture.

Best regards.
