The Bend term is much higher in cis-2-butene because the C(1)-C(2)-C(3) and the C(2)-C(3)-C(4) bond angles had to be deformed from their optimal value of 122.0° to 127.4° to relieve some of the steric crowding from the interaction of hydrogens on C(1) and C(4). WebBonded terms include several types of interactions, such as bond stretching terms, angle bending terms, dihedral or torsional terms, improper dihedrals, and coupling terms.
