Heating diazomethane generates nitrogen gas and a carbene. This question pertains to the structure and reactivity of the carbene species.
a) Draw a picture describing the geometry of the carbene that is generated, showing any orbitals that contain lone pairs or are empty.
b) On your picture from part a, indicate the types of orbitals that are present (s, p, sp 3, etc).
c) On your picture from part a, indicate in which orbital the lone pair resides.
d) On your picture from part a, identify any orbitals having nucleophilic character. Do the same for orbitals with electrophilic character.
