Question

functional groups confer specific chemical properties to the molecules of which they are a part. in this activity, you will identify which compounds exhibit certain chemical properties as well as examples of those six different compounds.
place one molecule and one chemical property to each bin. if one property can apply to more than one functional group, choose the best answer for each functional group.

contributes negative charge
acts as a base
acts as an acid
alcohol
carboxylic acid
aldehyde
thiol
amine
organic phosphate

Explanation:

Step1: Recall alcohol properties

Alcohols are generally neutral and do not contribute negative charge, act as a base or a strong acid. They can participate in hydrogen - bonding. But among the given properties, they do not have a strong characteristic match. However, they are not acidic or basic in the strong sense.

Step2: Recall carboxylic acid properties

Carboxylic acids ($R - COOH$) can donate a proton ($H^+$) in solution, so they act as acids.

Step3: Recall aldehyde properties

Aldehydes ($R - CHO$) are neutral functional groups and do not contribute negative charge, act as a base or a strong acid. They are mainly involved in oxidation - reduction reactions and nucleophilic addition reactions.

Step4: Recall thiol properties

Thiols ($R - SH$) are relatively stable and do not contribute negative charge in the way required here, nor are they strong bases or acids under normal conditions.

Step5: Recall amine properties

Amines ($R - NH_2$) have a lone pair of electrons on the nitrogen atom and can accept a proton ($H^+$), so they act as bases.

Step6: Recall organic phosphate properties

Organic phosphates ($R - O - PO_3^{2 - }$) have a negative charge due to the phosphate group.

Answer:

Functional Group	Chemical Property
carboxylic acid	acts as an acid
aldehyde	None of the given properties are a perfect match<br>
thiol	None of the given properties are a perfect match<br>
amine	acts as a base
organic phosphate	contributes negative charge
