Question

what is the iupac name of this compound? ch₃-ch₂-ch₂-ch₂-ch₂-ch₂-ch₃ a butane b heptane c octane d hexane

Explanation:

To name the compound using IUPAC rules, we first count the number of carbon atoms in the continuous chain. The formula \(CH_3 - CH_2 - CH_2 - CH_2 - CH_2 - CH_2 - CH_3\) has 7 carbon atoms. For alkanes (single - bonded carbon chains), the prefixes for the number of carbons are: 4 - but (butane), 6 - hex (hexane), 7 - hept (heptane), 8 - oct (octane). Since there are 7 carbons, the name is based on the 'hept' prefix for 7 carbons and the '-ane' suffix for alkanes.

Answer:

B. heptane
