Acetone, C3H6O, is commonly used as organic . Two important industrial chemicals, ethene, C 2 H 4, and propene, C 3 H 6, are produced by the steam (or thermal) cracking process: 2 C 3 H 8 ( g) C 2 H 4 ( g) + C 3 H 6 ( g) + CH 4 ( g) + H 2 ( g) For each of the four carbon compounds, do the following: (a) Draw a Lewis structure. ), 46(2), 1997, 314-318, In original 328-332. umn class: Standard non-polar; Column diameter: 0.32 mm; Column length: 25 m; Column type: Capillary; Start T: 110 C; CAS no: 67641; Active phase: SE-30; Carrier gas: He; Phase thickness: 1 um; Data type: Kovats RI; Authors: Golovnya, R.V.
