The correct IUPAC name of the followng structure is :
Open in App
Solution
The correct option is C 4,5-dimethyl-4-ethyldecane
The longest continuous carbon chain in the molecule has 10 C atoms and this chain is called the parent/ main/principal chain.
The branched carbon atoms get the lowest possible number.
If the same substituent occurs more than once in the molecule, then prefix di (for two), tri (for three), tetra(for four) are used to indicate how many times it appears. Here , methyl group occurs twice, so di prefix is used
The naming of the substituents should be in alphabetical order.
The correct IUPAC name of the compund is 4, 5-dimethyl-4-ethyl decane.
