Cl, having the atomic number 17, belongs to the halogen group in the periodic table. Molecular Cl is a strong oxidant due to the high electron affinity and electronegativity of Cl. Consequently, molecular Cl is rare in nature, and Cl−, which is highly soluble in water, typically dominates...
Later, in his studies on iodine and fluorine compounds, he attributed acidity to aparticularcombinationofhydrogenand the halogen, writing, “aciditydoesnotdependuponanypeculiarelementarysubstances, butuponpeculiarcombinationsofvarioussubstances”. 后来,在他对碘和氟化合物的研究中,他将酸性归因于氢和卤素的特...
The Halogen Occultation Experiment (HALOE) uses solar occultation to measure vertical profiles of O3, HCl, HF, CH4, H2O, NO, NO2, aerosol extinction, and temperature versus pressure with an instantaneous vertical field of view of 1.6 km at the earth limb. Latitudinal coverage is from 80 deg...
摘要: CF3CH2OH was found to be a useful solvent for the oxidative rearrangement reactions of aminals promoted byN-chlorosuccinimide, which proceedviathe intermediacy ofin situformed chloro-aminals and that produce 3,4-dihydroquinazolines.关键词:...
(Supplementary Fig.8). For these closed-shell molecules with highly polarized bonds (large electronegativity difference between O or N and H) as well as halogens and hydroxyl (Supplementary Fig.9), the 10-electron count rule has less practical applicability and the atomic charge of the dopant ...
In addition to long-lived ODS, emissions of very short-lived substances (VSLS) also contribute to the total halogen injection into the stratosphere and therefore to ozone depletion17,18,19,20. VSLS are tropospheric reactive halogenated compounds with lifetimes less than 6 months, emitted from ...
