CHM247H1 Chapter Notes - Chapter 10: Stereospecificity, Stereochemistry, Protic Solvent
Document Summary
Chapter 10: the chemistry of the alkyl halides. R x and ar x: where x = f, cl, br, i. Halogen compounds in human physiology: table salt is iodized to prevent goite thyroxine. Organo halides from marine organisms: almost 100 different organic halides have been isolated from edible red seaweed (asparagopsis taxiformis, dichlorodiphenultrichloroethane. Kills insects that spread diseases (eg/ malaria, typhys) Persists in environment, collects in fatty tissue. Interferes with egg-shell formation of eagles and hawks. Halides are important industrially: vinyl chloride (ch2 = chcl) polymerized to give pvc. Ccl4 an alkyl halide, cl is bonded to an sp3 carbon. F2c=cf2 a vinyl halide, f is bonded to an sp2 hybridized carbon (on an isolated double bond) C6h5-br an aryl halide, br is bonded to an sp2 hybridized carbon of an aromatic ring. Ir the c-x bond stretch appears in the fingerprint region (500-800 cm-1) hard to identify by ir.
