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. drag one molecule (white label) and one chemical property (blue label) to each bin.

I think we will have;
Alcohol is a highly polar and may act as a weak acid, functional group is OH
Carboxylic acid; acts as an acid, the functional group is COOH
Aldehyde; may be a structural isomer of a ketone, functional group C=O
Thiol; it forms disulfide bonds since it has a functional group S-H
Amine, this may act as a base, due to the functional group NH2
Organic phosphate ;it contributes a negative charge considering its functional group PO4

Ibelieve it is b. proton.hope my answer has you : )
