sigma bond वाक्य

उदाहरण वाक्य

1. An electrocyclic reaction is a pericyclic reaction involving the net loss of a pi bond and creation of a sigma bond with formation of a ring.
2. The cyclic oligomers form when the nitrogen of the amide forms a sigma bond to a lithium while the nitrogen lone pair binds to another metal centre.
3. The thiyl radical propagates with the alkene to form a carbon centered radical, the previous double bond now allows free-rotation around the sigma bond.
4. It was first reported in 1848 from the reaction of zinc and ethyl iodide, and was the first compound known to contain a metal carbon sigma bond.
5. This is contrasted by sigma bonds which form bonding orbitals directly between the nuclei of the bonding atoms, resulting in greater overlap and a strong sigma bond.
6. This is contrasted by sigma bonds which form bonding orbitals directly between the nuclei of the bonding atoms, resulting in greater overlap and a strong sigma bond.
7. A typical triple bond, for example in acetylene, consists of one sigma bond and two pi bonds in two mutually perpendicular planes containing the bond axis.
8. Molecules with rings have additional sigma bonds, such as benzene rings, which have 6 C " C sigma bonds within the ring for 6 carbon atoms.
9. Molecules with rings have additional sigma bonds, such as benzene rings, which have 6 C " C sigma bonds within the ring for 6 carbon atoms.
10. In coordination complexes, only the first or sigma bond between each ligand and the central atom counts, but not any pi bonds to the same ligands.
