How is C2H4 planar?
« on: September 01, 2005, 07:41:35 PM »
I have a homework question that asks why is C2H4 planar and C2H6 is not, but aren't both of them linear?

C2H4 is ethylene.

C2H6 is ethane

(i'm just imitating mitch :P )

C2H4 has a double bond between the carbon atoms, C2H6 has a single bond between the carbon atoms. Look up a general chemistry text for the rest of the answer.

sorry, maybe a silly question, but can C2H4 exist as staggered as well as the eclipsed conformation? wouldn't the staggered conformation be lower in energy and shouldn't it be the more predominant conformation.
