Hydrogen cyanide (HCN) also contains the bond between carbon and nitrogen but the bond is localized as its hydrogen atom cannot accommodate the double or triple bond. Pi bonds are formed when single bonded atoms still have leftover electrons sitting in p orbitals. Even in penta-1,4-diene, the electrons are still localized. b) I a, Which of the following bonds is expected to be the most polar? Explanation Basic carbon skeletons are made up of sigma bonds.
