Problem Details

Butadiene, C4H6, is a planar molecule that has the following carbon-carbon bond lengths:

The figure shows a molecule with the following structure: H2CCHCHCH2, with a double bond between the first and the second and also between the third and the fourth carbon atoms. The bond between the second and the third carbon atoms is single and has the length of 1.48 angstroms. Each double bond has the length of 1.34 angstroms.

Based on your answer for Part D, discuss what additional aspects of bonding in butadiene might support the shorter middle C-C bond.
