Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
IUPAC Nomenclature
IUPAC nomenclature is a systematic method for naming organic chemical compounds. It provides rules for constructing names based on the structure of the molecule, including the longest carbon chain, substituents, and their positions. Understanding these rules is essential for accurately identifying and communicating the structure of organic compounds.

Structural Formulas
A structural formula represents the arrangement of atoms within a molecule, showing how the atoms are bonded together. It can be depicted in various ways, including condensed structural formulas, which provide a simplified view of the molecule while retaining essential information about connectivity. This understanding is crucial for interpreting and drawing chemical structures.

Isomerism
Isomerism refers to the phenomenon where compounds have the same molecular formula but different structural arrangements or spatial orientations. This can lead to different physical and chemical properties. Recognizing isomers is important when analyzing compounds like 2,5,6-trimethylnonane and 4-ethyl-5,6-dimethyldodecane, as their names reflect distinct structural variations.

Textbook Question
Suppose a scientist repeats the Millikan oil-drop experiment but reports the charges on the drops using an unusual (and imaginary) unit called the warmomb (wa). The scientist obtains the following data for four of the drops: Droplet Calculated Charge (wa) A 3.84⨉10−8 B 4.80⨉10−8 C 2.88⨉10−8 D 8.64⨉10−8 (a) If all the droplets were the same size, which would fall most slowly through the apparatus?
