The carboxyl group is -COOH, where one of the oxygens is double bonded to the carbon and the other is single bonded to the carbon. The oxygen atoms are highly electronegative; they have a strong attraction for shared electrons. The carboxyl group is acid because the high electronegative oxygen atoms pull the electrons away from the H atom in the O-H bond. When the electrons are pulled away from the H, it leaves the group as an H+ ion. Thus, the -COOH group is acidic (donates a proton). Strong bases, like hydroxide, OH-, attract H+ ions. OH- has unpaired electrons on the oxygen that can be donated to H+ to make a bond.

1. The carboxyl group is -COOH, where one of the oxygens is double bonded to the carbon and the
other is single bonded to the carbon.
The oxygen atoms are highly electronegative; they have a strong attraction for shared electrons.
The carboxyl group is acid because the high electronegative oxygen atoms pull the electrons
away from the H atom in the O-H bond. When the electrons are pulled away from the H, it
leaves the group as an H+ ion. Thus, the -COOH group is acidic (donates a proton).
Strong bases, like hydroxide, OH-, attract H+ ions. OH- has unpaired electrons on the oxygen
that can be donated to H+ to make a bond.
