4,4'-Di-tert-butyl-2,2'-bipyridine
Abstract:
In the title compound, C(18)H(24)N(2), the mol-ecular unit adopts a trans conformation around the central C-C bond [N-C-C-N torsion angle of 179.2 (3)°], with the two aromatic rings almost coplanar [dihedral angle of only 0.70 (4)°]. The crystal packing is driven by co-operative contacts involving weak C-H⋯N and C-H⋯π inter-actions, and also the need to fill effectively the available space.

π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...
