Question #c1767

Answer 1

The given structural formula has got three `-CequivN` as functional groups.

Here we select a longest C-chain of 6 C-atoms and numbering is drawn from right so as to asign minimum locant `(3)` of the branching of `-CH_2CN " (cyanomethyl grouop)"`

So stemname is hex and its prefix name with locant will be 3-cyanomethyl.After the stemname two suffixes (1)ane for saturated class and (2)dinitrile for two `-CN` group should be added to get the complete IUPAC name which becomes

`color(red)"3-(cyanomethyl)hexanedinitrile"`
