Write lewis formulas that follow the octet rule for c2h4

Hello there!

This is an interesting thing I did last year in my Sophomore year.

Let me try this out!

First, we wanna start by drawing a standard structure with carbon in the middle, as hydrogen can only form one bond. (Please see pictue #1)

We know that the center carbon has too many bonds (maximum of 4), so we will shift two hydrogen over to the other carbon. (See picture #2)

Now each carbon has too few bonds, so we will make a double bond between them.

The last picture is the correct structure of C2H4, ethylene. The octet rule is kept.

I am terrible when it comes to drawing things. I hope this helps~!

Yes it would be a physical change.

Afraidsugar lol it’s the third one
