1.	What is the IUPAC name of the sown compound?(a) Propane-1,2,3-trial(b) 3-Formylpentan-1,5-dial(c) 2-(Formylmethyl)butan-1,4-dial(d) Propane-1,2,3-tricarbaldehydeThe question was asked in an international level competition.This intriguing question originated from Nomenclature and Structure of Carbonyl Groups topic in chapter Aldehydes, Ketones and Carboxylic Acids of Chemistry – Class 12
Answer» CORRECT answer is (d) Propane-1,2,3-tricarbaldehyde Explanation: There are three ALDEHYDIC groups present in the given compound and NONE of them have PREFERENCE over the other. The CHO groups are considered as SUBSTITUENTS with the parent chain containing only three carbon atoms. This is done to give identical treatment to all the aldehydic groups.
