Chemistry · Class 12 · CBSE — Biomolecules
The melting points of amino acids are higher than the corresponding halo-acids because
- amino acids exist as zwitter ions resulting in strong dipole – dipole attraction
- amino acids are optically active
- due to higher molecular mass of —NH2 group molecular mass of amino acids is higher
- they interact with water more than halo-acids and have salt like structure.
Answer
(A) amino acids exist as zwitter ions resulting in strong dipole – dipole attraction
