An amino acid under certain conditions have both positive and negative charges simultaneously in the same molecule. Such a form of amino acid is called

Assertion : Non-polar molecular solids have higher melting points than polar molecular solids. Reason : Non-polar molecular solids have weak London or dispersion forces between their molecules while polar molecules have strong dipole-dipole forces between their molecules.
