Question

Quizplus · Accepted Answer

The correct answer is D because the IUPAC nomenclature rules state that the prefixes "di" and "tri" should be used to indicate the number of identical substituents, while the prefix "ethyl" should be used to indicate a single ethyl substituent. Therefore, the name "3,3,5-triethyl-3-methylheptane" is incorrect and should be written as "3,3,5-triethyl-3-ethylheptane".
