Bond stereochemistry

WebBefore discussing the conformations, the term “Dihedral angle” should be discussed. It is an important stereochemical parameter. For an ethane molecule that rotates about its C − C C - C C − C single bond, two exactly opposite structures can be formed; the staggered conformation and eclipsed conformation. The difference in potential energies of these … WebThis occurs through a transition state in which the new Nu- C bond is partially forming at the same time that the old C -X bond is partially breaking and in which the negative charge is shared by both the incoming nucleophile and the outgoing halide ion.
