A general rule of thumb for bond length is that single bonds have the longest bond lengths while triple bonds have the shortest, with double bonds intermediate between the two. Another way to look at this bond length definition is: single bond>double bond>triple bond....
The average distance between the nuclei of two bound atoms in a molecule is called the bond length or bond distance in molecular geometry. It's a bond attribute that can be transferred between atoms of different fixed kinds, and it's not tied to the rest
We have successfully synthesized highly strained “core-shell”-type hydrocarbons and demonstrated that the C–C covalent bond can be expanded beyond 1.80 Å, which is 1.17 times greater than the standard length (1.54 Å). By the discovery of such a “hyper covalent bond,” the covalently ...
Note that in acetyl salicylic acid all of the carbon-carbon bonds in the 6-membered ring will actually be the same length (somewhere between the length of a C-C single bond and a C-C double bond). This is because the ring is said to be "aromatic." Essentially, the double bonds can...
键长(bond length)名词解释键长(bond length) 名词解释 键长是指化学键中两个原子之间的距离,是影响分子结构和性质的重要因素。 键长是指在分子中,两个原子之间的最短距离,通常用皮米 (pm) 作为单位表示。键长是分子结构中非常重要的参数之一,决定了分子的稳定性、化学反应性、光学和电学性质等。 键长的大小取决...

The scope of the palladium-catalyzed cyclization/dimerization of terminal allenyl ketones 1 to the 2,4-disubstituted furans 3 has been investigated. Simplified and improved conditions almost exclusively provided the dimer 3, accompanied by only traces of the easily separable monomer 2. The formation ...
A bond-order-bond-length-bond-strength (bond-OLS) correlation mechanism is presented for consistent insight into the origin of the shape-and-size dependence of a nanosolid, aiming to provide guidelines for designing nanomaterials with desired functions. It is proposed that the coordination number im...
