Parent chain = longest continuous carbon chain containing the carbonyl group; alkane, drop –e, add –al. ; The three oxygen sp 2 AO’s are involved as follows: The two unshared electorn pairs of oxygen occupy two of these AO’s, and the third is involved in sigma bond formation to the carbonyl carbon. stream
