  • Uw registration periodsThe melting and and boiling points range from very low (dispersion forces) to high (hydrogen bonds). The stronger the force is, the more energy is required to melt the solid or boil the liquid. ,Melting points. The amino acids are crystalline solids with surprisingly high melting points. It is difficult to pin the melting points down exactly because the amino acids tend to decompose before they melt. Decomposition and melting tend to be in the 200 - 300°C range. For the size of the molecules, this is very high.

    Sep 25, 2011 · The sugar melting study showed that the reason scientists and cooks haven't been able to isolate a definitive melting point for sugar is that sugar doesn't melt—it decomposes. This means that, rather than melting at one definitive temperature, sugar can become a liquid at different temperatures depending on heating rate.

    Hence, different compounds tend to have different melting points. A pure, nonionic, crystalline organic compound usually has a sharp and characteristic melting point (usually 0.5-1.0 C range). A mixture of very small amounts of miscible impurities will produce a depression of the melting point and an increase in the melting point range.
