Multiple-choice questions may continue on the next column or page find all choices before answering. The due time is Central time. 001 (part 1 of 1) 10 points An antibonding orbital is formed when 1. a free electron is present in the molecule. 2. an s-orbital overlaps a p-orbital. 3. the corresponding atomic orbitals are out of phase. 4. a p x-orbital overlaps a p z-orbital. 5. None of these is correct. 002 (part 1 of 1) 10 points Which of the following is TRUE about anti- bonding orbitals of the molecular orbital the- ory? 1. Unshared electrons are placed in anti- bonding orbitals. 2. Antibonding orbitals are higher in energy than their corresponding bonding orbitals. 3. Antibonding orbitals are made from the overlap of sigma and pi orbitals. 4. Although antibonding orbitals may ac- cept electrons, the electrons never remain for long....
