How do you identify whether a functional group is acidic or basic? For example, which of these functional groups are acidic and which are basic? - Hydroxyl - Carbonyl - Carboxyl - Amino - Sulfhydryl - Phosphate

Answer 1

The carbonyl group is likewise uncharged but slightly hydrophillic, whereas the carboxyl groups are typically acidic in nature.

Consequently, the compounds you provided can be categorized as:

Acids:-

#=># Hydroxyl #=>#Carboxyl #=>#Amino #=>#Phospate

Bases:

#=>#Carbonyl #=>#Sulfhydryl
