WebThe most important organic chemistry concepts. In organic compounds, C-C single bond is always a sigma bond. In the C=C double bond, the first bond is always a sigma bond, while the second is a pi bond. If a carbon atom is bonded to 2 other C-atoms, it must then have 2 H-atoms to complete its valency of 4 and attain a stable octet electronic ...
WebAn aromatic compound is a compound that contains one or more rings with pi electrons that are delocalized all the way around the ring or rings. Definition of terms: Ring – A structure of elements that are bound together to form a circular ring. Pi electrons – Electrons in a pi bond. Typically this is electrons in either a double or triple bond. WebFour Criteria for Aromaticity. The molecule is cyclic (a ring of atoms) The molecule is planar (all atoms in the molecule lie in the same plane) The molecule is fully conjugated (p orbitals at every atom in the ring) The …
