The melting points and solubility in water of amino acids are generally higher than that of the corresponding halo acids. Explain.A. amino acids exist as zwitter ions resulting in strong dipole-dipole attractionB. amino acids are optically activeC. due to higher molecular mass of -`NH_(2)` group molecular mass of amino acids is higherD. they interact with water more than halo-acids and have salt like structure .

1.	The melting points and solubility in water of amino acids are generally higher than that of the corresponding halo acids. Explain.A. amino acids exist as zwitter ions resulting in strong dipole-dipole attractionB. amino acids are optically activeC. due to higher molecular mass of -`NH_(2)` group molecular mass of amino acids is higherD. they interact with water more than halo-acids and have salt like structure .
Answer» Correct Answer - A Amino acids exist as zwitter ions, `H_(3)overset(+)N-CHR-COO^(-)` .Because of this dipolar salt-like character, they have strong dipole-dipole attractions . Hence, their melting points are higher than halo-acids .
