Question

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

Amino acids exist as zwitter ions, H3 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

Q. 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 $— N H_{2}$ group molecular mass of amino acids is higher

they interact with water more than halo-acids and have salt like structure.

Amino acids exist as zwitter ions, $H_{3} N + — C H R — CO O^{-} .$ Because of this dipolar salt-like character, they have strong dipole-dipole attractions. Hence, their melting points are higher than halo-acids
