Regioselectivity of Hydrogen Halide Addition When the alkene has an unsymmetrically located double bond, two constitutionally isomeric products are possible. As shown in Eq. 4.16, only one of the two possible products is formed from a 1-alkene in sig-nificant amount.

med-pathway.commolecular structure is the resonance hybrid and this structure represents the overall lowest total energy. Therefore, resonance is important for molecular stability. The resonance structures for benzene (C 6 H 6) are shown. Note that two resonance structures of benzene can be written in the Lewis dot format. As written, benzene has

Each p orbital contributes one electron, which means we have 6 electrons to accommodate (this is the same number of electrons as 3 bonds in the Kekulé structure). The 6 electrons fill the three lowest MO's, which happen to be the bonding MO's.
