d. In a stable molecule having an even number of electrons, all electrons must be paired.

Explanation:

Which of the following statements relating to molecular orbital (MO) theory is incorrect?

a. Combination of two 2p orbitals may result in either σ or π MOs. TRUE. If the atomic orbitals overlap frontally, a σ MO is produced while if the atomic orbitals overlap laterally, a π MO is produced.

b. Combination of two atomic orbitals produces one bonding and one antibonding MO. TRUE. The bonding MO has less energy than the antibonding MO.

c. A bonding MO is lower in energy than the two atomic orbitals from which it is formed. TRUE. The bonding MO is more stable than the individual atomic orbitals.

d. In a stable molecule having an even number of electrons, all electrons must be paired. FALSE. Let's consider, for example, the molecular orbitals of O₂: $\sigma_{2s}^{2} \sigma_{2s}^{*2} \sigma_{2pz}^{2} \pi_{2px}^{2} \pi_{2py}^{2} \pi_{2px}^{*1} \pi_{2py}^{*1}\sigma_{2pz}^{*}$

The electrons in the degenerated π* orbitals are not paired.

e. A species with a bond order of zero will not be stable. TRUE. For a species to be stable, the bond order must be higher than zero.

Answer from: Quest

Mass is the amount of matter in an object. weight is the measurement of the pull of gravity on an object. say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165) now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon. however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant. in conclusion it is possible for your weight to change as your mass remains constant.
