Give the Lewis dot structure of H2O. Write Lewis structures for the following: (a) HNNH (b) H2CNH (c) NO^- (d) N2 (e) CO (f) CN^- Write Lewis structures for the following: (a) SF2 (b) H2CCH2 (c) HNNH Give the Lewis structure for the polyatomic ion SO4-2. ...
Draw a skeleton structure of the molecule or ion, arranging the atoms around a central atom. (Generally, the least electronegative element should be placed in the center.) Connect each atom to the central atom with a single bond (one electron pair). Distribute the remaining electrons as lone...
wherein R11 and R12 are each independently, hydrocarbon C1-C20 and may be substituted at least once with a halide, hydroxyl, amine, amide, thiol, thioether, carboxylate, or a carbon structure of C1-C12 group which optionally may be substituted with any of the above preceding groups. 32. A...
Many chemists have focused on the development of new catalysts for exquisitely controlling chain growth, stereochemistry, and even the topological structure of polyesters. As a new strategy of combining the respective advantages of both metal complex catalysts and organocatalysts, Lewis pair complexes ...
To elucidate the inhibitory mechanism, it is necessary to determine and synthesize the minimum structure of the carbohydrate ligand; however, synthesis of the Lea tandem repeat has not been reported. We have recently developed and reported a new synthetic strategy for core 2 decasaccharide with ...

This is why the GeF4–AsH3 and GeF4–(AsH3)2 complexes are also analysed here, since in these species the interactions of germanium with halogen and arsenic centres mimic the interactions existing in the above-mentioned crystal structure. 2. Computational Details The calculations were carried out...
It was found that the strength of interaction increases with the increase of the atomic number of the tetrel element and that for heavier tetrel elements the ZFH3 tetrahedral structure is more deformed towards the structure with the planar ZH3 fragment. The results of calculations show that the ...
The main purpose of MOFs functionalization is to modify the properties of the ma- terials for the desired application [22]. In addition, linker functionalization can be a determining factor of the topology of the MOF structure [23,24]. For instance, it was found that the position of the ...
