The transition state for the addition is a nine-membered ring with chair conformation with partial single bonds and double bonds.
42.
The single bond has the capacity for rotation, a property not possessed by the double bond or the triple bond.
43.
Chauvin also explained how the carbene forms in the first place : by alpha-hydride elimination from a carbon metal single bond.
44.
Hydrogen and chlorine were originally used as examples of univalent atoms, because of their nature to form only one single bond.
45.
Ethane, a completely saturated compound, has only single bonds between its hydrogen and carbon atoms ( C 2 H 6 ).
46.
This minimum qualification to practice was the single bond between Sydenham and the College of Physicians throughout the whole of his career.
47.
Triphenylene is a fully benzenoid PAH, meaning its structure is composed only of full benzene rings interconnected by carbon carbon single bonds.
48.
Compounds in which krypton forms a single bond to nitrogen and oxygen have also been characterized, but are only stable below and respectively.
49.
The covalent radius is defined as half the bond lengths between two neutral atoms of the same kind connected with a single bond.
50.
Wavy single bonds are the standard way to represent unknown or unspecified stereochemistry or a mixture of isomers ( as with tetrahedeal stereocenters ).
