I was trying to name the following compound and I thought that if both the aldehyde group carbons should be included in the parent chain or I should go with the longest chain . I saw the solution for this and got two answers as I) 3-(Formylmethyl)hexanal and 2) 3-Propylpentanedial. Can someone please help me in naming it correctly??
IUPAC (2013) rule
P-44.1.1 The senior parent structure has the maximum number of substituents corresponding to the principal characteristic group (suffix) or senior parent hydride …
Therfore the latter name, 3-propylpentanedial, is correct.
