Carboxylic-acid nucleophile can substitute for carboxylic-acid hydroxyl group. Organic compounds {acid anhydride} can have last carbon in carbon chain double-bonded to oxygen atom and single-bonded to carboxylic acid. Acid anhydrides are colorless, smell bad like carboxylic acids, are highly reactive, are polar, are not acidic, are not basic, are not oxidizable or reducible, dissolve slightly in water, and are liquids unless more than six carbons.
Acid anhydrides {imide}| can be amides.
Organic compounds {acyl halide} can have last carbon in carbon chain double-bonded to oxygen atom and single-bonded to halogen. Acyl halides are colorful, have harsh and pungent and bad odor, are highly reactive, are polar, are not acidic, are not basic, are not oxidizable or reducible, dissolve slightly in water, and are liquids unless more than six carbons.
Organic compounds {amide}| can have last carbon in carbon chain double-bonded to oxygen atom and single-bonded to amino group. Amides include urea, phenobarbitol, and caffeine.
properties
Amides are colorful, have harsh and pungent and bad odor, are slightly reactive, are polar, are not acidic, are not basic, are not oxidizable or reducible, dissolve slightly in water, and are liquids unless more than six carbons.
bond
Amide bonds resonate, because double bond between carbon and oxygen can shift to nitrogen, making nitrogen positive, carbon positive, oxygen negative, and bond planar.
