Answer to: Draw the Lewis structure for the formaldehyde (CH2O) molecule. Be sure to include all resonance structures that satisfy the octet rule. which shows the partial double bond character of all three bonds. What is the Lewis Structure of formaldehyde, CH2O?
a. Draw these structures and use formal charges to predict the more likely structure for formaldehyde. b. Are the two structures you drew resonance forms of each other?
Formaldehyde, being the simplest aldehyde has a very simple structure. Its molecule consists of a carbon atom from which two hydrogen atom is attached by a single bond and a oxygen atom which is bonded to the carbon atom by a double bond. The detailed chemical and structural formula for formaldehyde (methanal) are given in the following points.

Thus it is also called dot and line structure. Here for Methanal or Formaldehyde, we have 12 valence electrons. As you know by now, the Hydrogen atom is always on the terminal side.

The Lewis structure for formaldehyde shows that the oxygen has two lone pairs and a bond to the central carbon. Again, this requires 3 equivalent bonding orbitals, sp2 hybridization.
