Trigonal Planar Electron Group Geometry
Methanal (Formaldehyde)
Ethene
(Ethylene)
120o
Perfect Trigonal Planar Arrangement
QuickTime™ and aTIFF (LZW) decompressor
are needed to see this picture.
The Double Bond in Ethene
sigma orbitalfor first part
of bond
pi orbitalfor second
part of bond
IsomerismSame number, kind of atoms
Different connectivity
Non-superimposable mirror images
Same connectivity but different spatial arrangement
e.g., cis,trans
