The melting points and solubility in water of amino acids are generally higher than that of the corresponding halo acids. Explain.

Text Solution

Verified by Experts

This is due to dipolar or zwitter ion structure of amino acids
`R-overset(H)overset(|)underset(""^(+)NH_(3))underset("| ")"C "-COO^(-)`
Therefore, like ionic compounds, amino acids have strong electrostatic attractions and hence have high melting points and are highly soluble in water.
