According to the frontier orbital theory, the symmetry of electrocyclic reactions is determined by:
 a. the total number of double bonds present in the molecule.
 b. the symmetry of the HOMO.
 c. the symmetry of the LUMO.
 d. proper orientation of the HOMO of one atom with the LUMO of the other atom.

Question 2

Which of the following statements is not true according to molecular orbital (MO) theory?
 a. Antibonding orbitals are higher in energy than the corresponding bonding orbital.
 b. The head-on overlap of an s and a p atomic orbital can produce a  molecular orbital.
 c. A  molecular orbital forms only from the combination of p atomic orbital wave functions.
 d. The subtractive combination of atomic orbital wave functions produces a bonding molecular orbital.
