Drawing trigonal planar

Postby AhYeon_Kwon_2H » Thu Dec 06, 2018 3:07 am

Do we have to draw the trigonal planar diagram with the shaded-in triangle and lined triangle, or would it be fine to just draw a regular Lewis structure with normal lines?

You do not need to include dashes or wedges in Lewis structures.

You don't have to draw wedges/lined triangles in a trigonal planar shape. The wedges and such indicate that the bond is 3D (either "coming out" of the paper or "going into" the paper), but all four atoms in a trigonal planar molecule lay flat.

It can be helpful conceptually if you know how to draw them but they are not required on tests.
