Identify the functional groups listed in the options. A functional group is a specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
Examine the hydroxyl group (-OH). This group consists of an oxygen atom bonded to a hydrogen atom and is commonly found in alcohols. It is a polar group and can form hydrogen bonds, affecting the solubility and reactivity of organic molecules.
Consider carbon dioxide (CO2). This is a molecule consisting of one carbon atom double bonded to two oxygen atoms. It is not a functional group but rather a small molecule often involved in respiration and photosynthesis.
Evaluate the sodium ion (Na+). This is a positively charged ion, not a functional group. It is typically involved in ionic compounds and does not participate in the covalent bonding characteristic of organic molecules.
Assess the chloride ion (Cl-). This is a negatively charged ion, similar to the sodium ion, and is not considered a functional group in organic chemistry. It is often found in ionic compounds.
