Problem: Butadiene, C4H6, is a planar molecule that has the following carbon-carbon bond lengths:Predict the bond angles around each of the carbon atoms.

FREE Expert Solution

We’re being asked to identify the bond angle around each carbon atom in butadiene (C4H6). We will determine the bond angles using the following steps::


Step 1: Determine the number of electron groups around the indicated atom.

Step 2: Determine the electron geometry and bond angle using this:


Electron Regions          Electronic Geometry          Bond Angles

2                                      linear                                    180˚

3                                      trigonal planar                      120˚

4                                      tetrahedral                            109.5˚

5                                      trigonal bipyramidal              90˚, 120˚, and 180˚

6                                      octahedral                            90˚ and 180˚

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.

Predict the bond angles around each of the carbon atoms.
