The IUPAC nomenclature of the organic compound with the above structural formula is

Answer Details

The organic compound with the given structural formula is a branched chain alkane with a total of eight carbon atoms. To name the compound using IUPAC nomenclature, we need to identify the longest continuous carbon chain, which in this case is five carbons long. We number the carbon chain from the end that gives the substituent with the lowest possible number. In this case, we can number the chain from either end but we get the numbering 2, 5 for the substituents. The compound has one ethyl group (a two-carbon chain attached to the second carbon atom of the main chain) and two methyl groups (one attached to the second carbon atom and another to the fifth carbon atom of the main chain). Therefore, the IUPAC name of the compound is 3-ethyl-2,5-dimethylhexane. Thus, the correct option is: 3-ethyl-2,5-dimethylhexane.
