The correct name of the given compound is 3,3-dimethyl-4-ethyloctane .
The given compound is 3,3-methyl-4-ethyloctane .
The given name is wrong according to the IUPAC nomenclature because the numbering of carbon atom in a ring should start from the carbon atom which is bonded to the functional group to give least numbering to the functional group and is there is two same group in one number then , the nomenclature should be like 1,1-di and 2,2,2 tri or 2,3,4-tri .
Here the compound has two methyl group attached to the number 3 carbon thus during nomenclature , the nomenclature should start with 3,3-dimethyl . then the ethyl group then the long chain should attach .
thus the name is like 3,3-dimethyl-4-ethyloctane .
Hence , the answer is 3,3-dimethyl-4-ethyloctane .
IUPAC nomenclature :
