Overview
The cyanohydrin of propanone, retaining two equivalent methyl groups.
The former carbonyl carbon is bonded to hydroxyl, nitrile and two methyl groups. It is not stereogenic because the methyl groups are identical. The additional nitrile carbon makes this a four-carbon molecule even though the parent ketone contains three carbons.
