WebAug 21, 2024 · Primary and secondary amides can have hydrogen bonding, and therefore have high boiling points and melting points. Tertiary amides cannot hydrogen bond, so their boiling points are lower than those of similar size amides. Primary, secondary, and tertiary amines can hydrogen-bond with water, so the lower members of the series are … WebA giant covalent structure has many strong bonds holding it together. The next highest melting points are found in some metals, notably transitional metals. ... These have stronger dipole-dipole interactions, called hydrogen bonds, in addition to dispersion forces. Their boiling points are higher than both similiar sized non-polar, or polar ...
