Chapter 8, Problem 16E

Two important industrial chemicals, ethene, ${\text{C}}_2{\text{H}}_4$, and propene, ${\text{C}}_3{\text{H}}_6$, are produced by the steam (or thermal) cracking process:

$2{\text{C}}_3{\text{H}}_8\left(g\right)\to {\text{C}}_2{\text{H}}_4\left(g\right)+{\text{C}}_3{\text{H}}_6\left(g\right)+{\text{H}}_2\left(g\right)$

For each of the four carbon compounds, do the following:

(a) Draw a Lewis structure.

(b) Predict the geometry about the carbon atom.

(c) Determine the hybridization of each type of carbon atom.
