WebA WebAug 12, 2024 · Which of the two ‘C’ groups is priority #2, the aldehyde or the CH 2 OH? To determine this, we move one more bond away from the chiral center: for the aldehyde we have a double bond to an oxygen, while on the CH 2 OH group we have a single bond to an oxygen. If the atom is the same, double bonds have a higher priority than single bonds.
