have neurotransmitter-like properties‚ and many additional true neurotransmitters may await discovery. The first of these families‚ and the group about which most is known‚ is the amine neurotransmitters‚ a group of compounds containing a nitrogen molecule which is not part of a ring structure. Among the amine neurotransmitters are acetylcholine‚ norepinephrine‚ dopamine‚ and serotonin. Acetylcholine is possibly the most widely used neurotransmitter in the body‚ and all axons that leave the

tests previously learned are not enough to identify organic compounds. Functional groups present in organic compounds must be identified. Acetyl chloride test can be used for alcohols‚ amines and phenols. A positive result for alcohol is the formation of a separate layer‚ and is usually accompanied by heat. For amines‚ solid amides were formed. Alkaline

function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine. Aside from Caffeine‚ Acetaminophen has one amide functional group. This makes it the second most polar analgesic. In addition‚ Acetylsalicylic Acid has an ester group. Since ester group is not as polar as either amine or amide groups‚

of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such as carboxylic acids (acidic) and amines (basic). Since the compounds are being separated based on solubility and melting points‚ they must be in a solvent that is immiscible in nature; for example‚ ether and water. The organic acid compounds would be insoluble in water but is often soluble
