They also form when primary alcohols react with cold potassium permanganate.
According to IUPAC  (I-U-pack)  nomenclature rules, this functional group has ultimate priority in determining the base name of a compound. Anhydrides and nitriles are classified as derivatives of these compounds, which form when water kicks out chlorine in an acyl chloride. They also form when primary alcohols react with cold potassium permanganate. A common example of resonance is the rationale that these compounds have more stable conjugate (*)  bases than alcohols. These functional groups appear at the C terminus of all proteins. These compounds, which form dimers in water, react with alcohols to form esters and form peptide bonds with amines. They have pKa values around five. For 10 points, name these compounds that have a COOH functionality, which makes them acidic.
