Here are the essential concepts you must grasp in order to answer the question correctly.
Lewis Structures
Lewis structures are diagrams that represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist. They are essential for visualizing the arrangement of atoms, the distribution of electrons, and the types of bonds (single, double, or triple) in a molecule. Understanding Lewis structures helps predict molecular geometry, reactivity, and properties.

Functional Groups
Functional groups are specific groups of atoms within molecules that have characteristic properties and chemical reactivity. In organic chemistry, recognizing functional groups like esters, alcohols, and carboxylic acids is crucial for classifying compounds and predicting their behavior in chemical reactions. For example, in (CH3)2CHCOOCH3, the COOCH3 part is an ester group.

IUPAC Nomenclature
IUPAC nomenclature is a systematic method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry. It provides a standardized way to name compounds based on their structure, ensuring clear communication. Understanding IUPAC rules helps in identifying and classifying compounds, such as recognizing that CH3CHCHCOCl contains an acyl chloride group.
