Brodbelt CH301 Homework 6 Due October 24, 2007 at 11:00 PM 001 (part 1 of 1) 10 points Which of the following is TRUE about anti- bonding orbitals of the molecular orbital the- ory? 1. Although antibonding orbitals may ac- cept electrons, the electrons never remain for long. 2. Antibonding orbitals are made from the overlap of sigma and pi orbitals. 3. Antibonding orbitals are higher in energy than their corresponding bonding orbitals. correct 4. Unshared electrons are placed in anti- bonding orbitals. 5. The strongest bonds between atoms have no electrons in antibonding orbitals. Explanation: Antibonding orbitals are higher in energy than their corresponding bonding orbitals. Molecules can exist with electrons in anti- bonding orbitals, as long as the molecule does not place as many electrons in antibonding orbitals as there are in bonding orbitals....
