part c (3 of 3) - classifying molecules by their functional groups
3 tries left
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.

may be a structural isomer of a ketone
is polar and makes compounds more soluble in water
alcohol
carboxylic acid
acts as an acid
aldehyde
thiol
amine
acts as a base
organic phosphate
contributes negative charge

Explanation:

Step1: Identify alcohol

Alcohol has a -OH functional group. The molecule with -OH group is placed in alcohol bin and its property is "is polar and makes compounds more soluble in water" as the -OH group can form hydrogen - bonds with water.

Step2: Identify carboxylic acid

Carboxylic acid has a -COOH functional group. Its property is "acts as an acid" due to the ability to donate a proton (H⁺) from the -COOH group.

Step3: Identify aldehyde

Aldehyde has a -CHO functional group. There is no molecule with -CHO shown in the given structures, so we can't place a molecule here. But its general property is related to its carbon - oxygen double bond and hydrogen on the carbonyl carbon.

Step4: Identify thiol

Thiol has a -SH functional group. There is no -SH containing molecule shown, so we can't place a molecule here. Its general property includes reactivity due to the -SH group.

Step5: Identify amine

Amine has a -NH₂ (or other amino - related) functional group. The molecule with -NH₂ group is placed in amine bin and its property is "acts as a base" as the nitrogen in -NH₂ can accept a proton (H⁺).

Step6: Identify organic phosphate

Organic phosphate has a phosphate group (-PO₄). The molecule with phosphate group is placed in organic phosphate bin and its property is "contributes negative charge" as the phosphate group can ionize and carry a negative charge.

Answer:

Alcohol: Molecule with -OH group, is polar and makes compounds more soluble in water
Carboxylic acid: Molecule with -COOH group, acts as an acid
Aldehyde: No molecule shown
Thiol: No molecule shown
Amine: Molecule with -NH₂ group, acts as a base
Organic phosphate: Molecule with -PO₄ group, contributes negative charge
