The number of bonds, whether single, double, or triple, is determined by the number of shared electrons between atoms. The covalent bonds comprise single, double, and triple bonds in it. The number of shared electrons is the major distinction between single double and triple bonds. A single ...

Changes in weighed average class chain lengths (c) and number of double bonds (d) indicate species remodeling within a lipid class. Note that the number of double bonds in (d) does not contain the triple bond(s) of the alkyne fatty acid used for labeling. The bars represent the mean ...
Nitrogen atom widely exists in many organic molecules and biomacromolecules. Therefore, the formation and transformation of C–N bonds are one of the most attractive topics in organic synthetic chemistry. Although a few wo
On the basis of these results, we propose this bond as a member of silicon–silicon bonds such as single bonds, double bonds10,11,12,13,14,15,16,17, and triple bonds18,19,20,21,22. Results Synthesis, structure, and properties The reduction of trans-1,3-dibromo-1,2,2,3,4,4-...
