Draw the Lewis structure for each organic compound from its condensed structural formula. c. CH₃COCH₃

Lewis structures are diagrams that represent the bonding between atoms in a molecule and the lone pairs of electrons that may exist. They use dots to represent electrons and lines to represent bonds between atoms. Understanding how to draw Lewis structures is essential for visualizing molecular geometry and predicting reactivity.

A condensed structural formula provides a shorthand way of representing the structure of a molecule, showing how atoms are connected without depicting all the bonds explicitly. For example, in CH3COCH3, the formula indicates that there are two methyl groups (CH3) attached to a carbonyl group (C=O), which is crucial for understanding the molecular structure before drawing the Lewis structure.

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In the case of CH3COCH3, the carbonyl group (C=O) is a functional group that defines the compound as a ketone, influencing its chemical behavior and properties. Recognizing functional groups is vital for predicting reactivity and understanding organic chemistry.
