ow that we've reviewed the various bonding models, we are ready to examine organic compounds in respect to their structure, reactions, properties, and appli cations. Were we to list the physical and chemical properties of each of the more than million organic compounds separately, it would tax the capacity of even a pow- erful computer. Yet someone who is trained in organic chemistry can simply look at the structure

SOLUTIONS TO TEXT PROBLEMS 5.1 (b) Writing the structure in more detail, we see that the longest continuous chain contains four carbon atoms

8. 1 Water molecules form an open crystalline structure in ice When water freezes. the water molecules arrange themselves in a six-sided crystalline structure. Increased structural orderliness usually means increased density. Solids and crystals have high structural orderliness and are thus denser than liquid and non-crystalline materials. But water is exception

X-Ray diffraction is an important and powerful tool for determining the solid state structure of compounds. Modern advances have made data collection and structure solution almost routine for many small molecules To use this technique, however, good quality single crystals are still needed. In this exercise you will experiment with the art of growing single crystals

Histones vs Nonhistone Histones are small, very basic proteins rich in lysine and arginine. The histones are the basic building blocks of chromatin structure. The nucleoids of prokaryotic cells also have proteins associated with DNA, but these proteins are quite different from the histones and do not seem to form a comparable chromatin structure. Nonhistone chromosomal proteins-The histones are accompanied
