In organic chemistry, two molecules that can besuperimposedon each other, through rotation of bonds (i.e. conformational changes) or through rotation of the molecule itself,are considered to be the same molecule. In other words, in organic chemistry, molecules that are “identical twins” are n...

Modifying the tagged group of the ligand hanging in the channels by reaction has dominated the early days of PSM, given the convenience to draw lessons from synthetic organic chemistry. Recently, the kinetically labile nature of metal–ligand coordination bonds in MOF has enabled exchanging both the...

Based on the atomic ratio of the elements obtained by the elemental analysis method, we can assume that the system of conjugated aromatic bonds is well developed in biochars. The degree of aromaticity indicates that aromatic compounds prevail in the studied sorbents, mainly in wood biochar. Accord...
Similarly, electrons in the outermost shell of N2 are five, it needs 3 convalent bonds.氧的最外层电子数是六,所以要填补到8个的稳定状态,就需要两个共价键。氮的最外层电子数是5,所以要三个共价键3.这个我不知道。。不过,这里有详解。。只要你耐心看吧http://intro.chem.okstate.edu/1314F00/Lectur...

A method of identifying a subject having a urinary tract infection posing a significant risk of dangerous sequalae is described. The method includes obtaining a urine or fecal sample from the subject; determining the predominant LPS O-antigen serotype in the sample; and comparing the predominant LP...
