Look at the drawing of the butadiene molecule.Which statement about this molecule isnottrue?

By valence bond theory (and the drawing), thereare four electrons to account for in the molecule.

Valence bond theory says that all the carbon atomshave hybridized sp²orbitals.

There are p orbitals (in the carbon atoms) whoseaxes actually are perpendicular to the page.

The resonance that occurs in the butadienemolecule causes the carbon-carbon bond lengths to constantlychange.

We learned that four new molecular orbitals are created from thep orbitals for each carbon atom in the butadiene molecule (the axesperpendicular to the page). Which statement about these molecularorbitals is NOT true?

A.The four molecular p orbitals of the four carbon atoms can belined up parallel in order to create four new molecularorbitals.

B. The electrons in the new molecular orbitals benefit becausethey are not confined to just one atom.

C. The electrons, because of the new molecular orbits, arespread out over the entire molecule.

D. As a result of the new molecular orbitals, the bond betweenthe second and third carbon atoms is not really a single bond. Infact, the bond should be shorter.
