Chirality is the right or left 'handedness' of an object. A chiral object can't be superimposed on its mirror image, while an achiral object can be superimposed on its mirror. This lesson explores chirality as a property of molecular structures. ...

C项的原文对应信息为“a growing number of organizations have begun shifting from traditional hierarchical structures to self-organized and collaborative networks,using wiki software”。A项中,关于联合国这项新措施的结果我们尚未得知。B项表述错误。D项的表述并没有在文章中出现。故选C。 A white kid sells...
Which of the following compound is not chiral? Thus, 3-bromopentane is not a chiral compound. Therefore, the answer to this question is option C, 3-dibromopentane. Note: The compounds which are not chiral are also called achiral compounds....
PROBLEM TO BE SOLVED: To provide a method for oxidizing olefinic hydrocarbons in which conversion and the yields of reaction products are improved, and selectivity of carbonyl compounds or epoxides is optionally improved, without using reducing agents such as hydrogen accompanied by a danger of explos...

examined into the intestinal system. Claudin expression habits have, as an example, been found is impacted in disease and infection, or in cancer. Within the kidney, a deeper knowledge of the complexities plus the ramifications of claudin appearance alterations is just emerging. Little is well kno...
(MHPs) including chiral natural ligand molecules tend to be obviously sensitive to left- and right-handed circular polarized light, possibly enabling discerning circular polarized photodetection. Here, the photoresponses in chiral MHP polycrystalline slim films made of ((S)-(-)-α-methyl benzylamine)...
of grignard reagent was cooled to -20° C. and a solution of (-)-anhydroecgonine methyl ester (21.7 g, 120 mmol) in 100 ml absolute diethyl ether was added over 1/2 hour. The reaction was stirred one hour at -20° C. and the reaction was quenched in one of the following two ...
