May 18, 2014The VSEPR model predicts that CH₂O is trigonal planar with bond angles of about 120 &. We must first draw the Lewis structure for CH₂O. There are three electron regions around the central carbon atom. The VSEPR model states that the electron regions around an atom spread out to make each one as far from the others as possible. In formaldehyde, the central atom has three electron …
