Certainly! Common functional groups in organic chemistry include hydroxyl (-OH) in alcohols (e.g., ethanol), carbonyl (C=O) in aldehydes (e.g., formaldehyde) and ketones (e.g., acetone), carboxyl (-COOH) in carboxylic acids (e.g., acetic acid), amino (-NH₂) in amines (e.g., ammonia), and phosphate (-PO₄³⁻) in phosphates (e.g., ATP). Other examples are methyl (-CH₃) in methyl groups, ethyl (-C₂H₅) in ethyl groups, and halogens (e.g., -Cl, -Br, -F) in halides. These functional groups impart specific chemical and physical properties to organic compounds, influencing their reactivity and roles in biological, medicinal, and materials chemistry.
