The melting points and solubility in water of amino acids are higher than those of the corresponding haloacids. Explain. |
| Answer» Solution :The amino ACIDS EXIST as zwitterions, `H_(3) overset(+)(N)-CHR-COO^(-)`. Due to this dipolar salt like character they have strong dipole - dipole attractions or electrostatic attractions . Therefore, their melting points are higher than HALOACIDS which do not have salt like character. Further , due to salt like character , they intersect strongly with `H_(2)O`. As a result , solubility in WATER of amino acids is higher than that of the corresponding haloacids which do not have salt like character. | |
