hw 4.21 a

Postby Emely Reyna 1F » Sun Jun 03, 2018 8:36 pm

problem 4.21 asks to write the lewis structure and give the approximate bond angle of:

C2H4

I can draw the structure easily enough, with the two bonded C's in the center but I'm having trouble understanding why it is a trigonal planar, when there five bonds?

It is trigonal planar because each carbon has three electron densities attached to it.

The shape is called Trigonal Planar because there are two center atoms, each with 3 regions of electron density. The Shape of the molecule is thus more accurately two trigonal planar shapes.
