Consider the H-M-H angle around the central atom, M, in the compounds and ions below. Which is the correct order of increasing angle? {eq}NH_{3}, H_{2}S, CH_{3}+ {/eq} 1. {eq}NH_{3} < H_{2}S < CH_{3}+ {/...
For the carbonate ion, {eq}CO_{3}^{2-} {/eq}, draw all the resonance structures. Identify which orbitals overlap to create each bond. Orbital Overlapping: Orbital overlapping refers to the interaction of atomic orbitals from different atoms to form covale...
Unpaired electrons can be considered as those electrons that alone can occupy the atomic orbitals. An atomic orbital has the capacity to contain two electrons but if it contains only one electron then that electron is called an unpaired electron....
Atoms in carbon cages as a source of interstellar diffuse lines A model to describe the resonance absorption lines of various atoms trapped in closed carbon cages is presented. These systems may be responsible for some ... JL Ballester,PR Antoniewicz,R Smoluchowski - 《Astrophysical Journal》 被...
sliding at a high speed is required to retain its lubricating performance and abrasion resistance for a long period of time, comprising a host-guest complex composed of a lubricant molecule as a guest molecule and a multidentate ligand as a host compound to form the complex with the guest ...
The elucidation of the structure of compound 3b, both in the solid state and in solution, has revealed that nN-σ*CH2-N3R+ orbital overlap confirms that an anomeric effect is present in the ammonium salt. This straightforward, one-step process provides a convenient preparative method for mono-...
