Which of the following statements is not true of amino acids?

Question

Quizplus · Accepted Answer

Amino acids are typically less acidic than carboxylic acids (choice A is true), they do show an IR absorption near 1720 cm-1 in acid solution (choice B is true), they are typically soluble in water but not in non-polar organic solvents (choice C is true), but they are not more basic than amines - amines have a lone pair of electrons that can accept a proton, while amino acids have a lone pair of electrons that can donate a proton (choice D is false). In basic solution (pH ~ 12), amino acids would show an IR absorption near 3300 cm-1 due to N-H stretching vibrations, as the amino group becomes more protonated (choice E is true).
