Jun-Hong Chou,, … WebFor a carbon with 1 double bond and 2 single bonds, the orbitals will become 33% "s" and 66.7% "p" making it "sp2." If there is a triple bond and a single bond, the orbitals will adjust again to become 50% "s" and 50% "p." So to summarize - You can find sp3 bonding when a carbon has 4 single bonds. You can find sp2 bonding when carbon has a ONE ...
WebYou have the two nitrogens joined by exactly the same arrangement of orbitals as in ethyne and HCN, but this time there is a lone pair of electrons at each end of the molecule. Any triple bond will be made of a sigma bond and two pi bonds at right angles to each other.
