WebThe pharmaceutical success of atorvastatin (ATV), a widely employed drug against the “bad” cholesterol (LDL) and cardiovascular diseases, traces back to its ability to scavenge free radicals. Unfortunately, information on its antioxidant properties is missing or unreliable. Here, we report detailed quantum chemical results for ATV and its ortho- … WebThe ortho and para hydrogen differ in the nature of the spin of protons. In ortho hydrogen, the spin of the proton are in the same direction, while in para-hydrogen the spin of the proton are in opposite direction in hydrogen molecules.

Webdeactivating or ortho,para-directing and ring-activating (Table 4). Exceptions are the halogens, which are ortho,para-directing but ring-deactivating. These effects must be taken into account in devising syntheses of aromatic compounds. Benzene is a major commercial chemical–a source of styrene, phenol, other aromatics, acetone, and cyclohexane. WebFor both para- and ortho- hydrogens, the two electrons are sitting in the same ground state molecular orbital of the hydrogen molecule, so I dont think there is a difference. The energy of a hydrogen molecule arises from its translational, rotational and vibration kinetic energy.
