(a) Draw a Lewis diagram for formaldehyde (H,CO), and decide the hybridization of the central carbon atom. (b) Formulate the molecular orbitals for the molecule. (c) A strong absorption is observed in the ultraviolet region of the spectrum and is attributed to a → T* transition. Another, weaker transition is observed at lower frequencies. What electronic excitation causes the weaker transition?
