Topic #3: Why are the reactions of aldehydes and imines very similar? Be very specific. First, recall that aldehydes are carbonyl molecules, but have an RCHO structure. There is only one alkyl group bonded to the carbon of the carbonyl group. Meanwhile, ketones are carbonyl molecules with an R2CO structure. These molecules differ on the basis of the substituents bonded to the carbon atom of the carbonyl. Now, imines are characterized by their C=N bond, in contrast with carbonyls that have a C=O bond. At this point, I think it is important to note that there are different types of imines, a difference which I admittedly took for granted when I was researching my response to this discussion question! According to Wikipedia (Imine entry, referenced below), there are aldimines, which have the structure RCHNH (primary aldimine) or RCHNR’ (secondary aldimine). Then we have ketimines, which are imines with the structure RCRNH (primary ketimine) or RCRNR (secondary ketimine). Aldimines are more analogous to aldehyles, whereas ketimines are more analogous to ketones
