The melting points of amino acids are higher than the corresponding halo-acids because
A
amino acids exists as zwitter ions resulting in strong dipole-dipoles attraction
B
Amino acids are optically active
C
Due to higher moleculear mass of 
group molecular mass of amino acids is higher.
group molecular mass of amino acids is higher.
D
They interact with water more than halo – acids and have salt like structure
Text Solution
Verified by ExpertsThe correct answer is:
A
Amino acids exist as zwitter ions, 
Because of this dipolar attractions. Character, they have strong dipole-dipole attractions. Hence, their melting points are higher then halo-acids.
