Understand that organic compounds are primarily classified based on their functional groups, which are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
Recognize that functional groups are key to determining the properties and reactivity of organic compounds, making them a primary method for classification.
Consider that while molecular weight, color, and boiling points can provide information about a compound, they are not as fundamental to classification as functional groups.
Functional groups include common groups such as hydroxyl (-OH), carbonyl (C=O), carboxyl (-COOH), amino (-NH2), and others, each imparting specific properties to the molecules they are part of.
By identifying the functional groups present in a compound, scientists can predict its reactivity and interactions with other substances, which is crucial for understanding and utilizing organic compounds in various applications.
