WebHydrogen bonding between the 1,3-dipole and acetylene is generally stronger, which leads to higher reaction barriers in the acetylene case. Elementary differences are found with regard to charge transfer, charge polarization, rehybridization, and bond formation of the two dipolarophiles, which explain their different reaction energies.

WebA bond angle is the angle between any two bonds that include a common atom, usually measured in degrees. A bond distance (or bond length) is the distance between the nuclei of two bonded atoms along the straight line joining the nuclei. Bond distances are measured in Ångstroms (1 Å = 10 -10 m) or picometers (1 pm = 10 -12 m, 100 pm = 1 Å).
