Question

Answer if the each of the following statements true (T) or false (F). The name of CH_2 = CHCH_2Na is propylsodium. Ethyl bromide is more reactive than Ethyl chloride to react with Mg. Organozinc reagent, ICH_2Znl is useful reagent to prepare cyclopentane Compounds from alkenes and CH_2I_2. Organocopper reagents are unique reagents to form alkanes. Platinum-catalyzed cross-coupling reactions to form biphenyls are known separately as the Stille, Negishi, Suzuki and Heck couplings. The difference in energy Delta E of two nuclear spin states is inversely proportional to the strength of the applied magnetic field. In NMR, the dependence of the resonance position of a nucleus that results from molecular environment is called chemical shift. In NMR, an external magnetic field affects the motion of the electrons in a molecule and the induced magnetic field of the electrons in the carbon-hydrogen bond reinforces the external magnetic field. Infrared spectroscopy is a useful tool to determine presence of some of unique functional groups in a molecule. From a biochemical perspective, the most important oxidation is the conversion of thiols to sulfoxides.
