Where self-inclusion is ineffective, the microcavities predictably assimilate the intrinsic cavitand molecular cavity, yet the ultimate size and shape of cavities are also strongly influenced by crystal packing. It is demonstrated that some cavitand solvates, CH2Cl2@H,Me,CH2, xH(2)O@Me,Et,SiMe2,...
Draw the Lewis structure for CH2Cl2 and state its molecular geometry. Is it polar or nonpolar? Draw the Lewis structure for SO2. Show all lone pairs and locate any formal charges. Determine the number of valence electrons, give t...
The resulting stator assembly adopts the shape of a three-bladed propeller. One end of the rotor is inserted into one of the grooves, or clefts, formed by two adjacent tilted phenyl blades. The rotor and stator components of Motor I may bear additional substituents or be fused to additional...
PS (Mw ca. 15,900) was dissolved in toluene or CH2Cl2 to from 16.7 and 28.6 wt% polymer solutions. These solutions were then drawn into a membrane on a glass substrate using a doctors blade set at a gate height of 254 or 381 mm. After the membranes were cast, the solvent was ...
Provide the following information for the compound CH2Cl2. a. total number of valance electrons b. name of the electron geometry c. number of bonds attached to the central atom d. number of electron pairs on the central atom e. name of the ...
X-ray crystal structures of [CpRu(η2-dmpm)(PPh3)]Cl and [CpRu(μ-dmpm)2Pt(PPh3)]PF6·CH2Cl2 CpRuCl(PPh 3 ) 2 reacts sequentially with bis(dimethylphosphino)methane (dmpm) to yield [CpRu(η2-dmpm)(PPh3)]Cl (1) and then [CpRu( η 2 -dmpm)( η 1 -dmpm)]Cl ( 2a ) from ...
Determine the number of lone pairs around the central atom in CH2Cl2. 1. What is the electron-pair geometry for Xe in XeCl2? 2. There are ___ lone pair(s) around the central atom, so the molecular geometry of XeCl2 is ___. Identify the ...

The mixture was stirred for 30 minutes before being concentrated and co-evaporated 5 times with 20 mL of CH2Cl2 in order to remove the excess of TFA. The residue was then diluted in CH2Cl2 (20 mL). To this solution was added NH4PF6 (78 mg, 0.48 mmol, 5 equiv) and MilliQ H2O (10...
