Unformatted text preview: 2 d • In triple bonds, as in acetylene, 2 sp orbitals from a sigma bond between the carbons, and 2 pairs of p orbitals overlap in pi fashion to form the two pi bonds o Sp-2 pi bonds o Sp 2-1pi bond o Sp 3-0 pi bonds • In reality each of the 4 atoms in the Nitrate ion has a p-orbital • The p orbitals on all 3 oxygens overlap with the p orbital on the central nitrogen • The organic molecule benzene has 6 sigma bonds and a p orbital on each carbon atom • The reality the pi electron in benzene are not localized, but delocalized • Cis- isomer because the chlorines are on the same side of the double bond • Trans-isomer because the chlorines are on opposite sides of the double bond...
