I have a question regarding hybrid vs atomic orbitals:
1) What would be the hybridizations of C and O in the molecule H2CO? It asks to draw an electron orbital diagram (with arrows) of all the electrons in C before and after hybridization.
2) Draw a diagram of the H2CO molecule showing the overlap of orbitals between the C and O atoms that make up the sigma (σ) and pi (π) bonds. Which orbitals make up the σ bond? Which ones form the π bond?
