Chapter 2 Number 42: Naming an aldehyde

Postby jennifer_zhou2C » Thu Feb 25, 2016 10:55 am

The question asks: A methyl derivative of citronellal is being tested as a stronger insect repellent against mosquitoes that carry malaria. Write the IUPAC name for: o=CH-CH(CH3)-CH(CH3)-CH2-CH2-CH=C(CH3)2.
I got 2,3,7-trimethyloct-6-en-1-al. The book states that the answer is 2,3,7-trimethyloct-6enal. Why would you not put the one? Does putting the one make it wrong?

If there is no number, it is conventionally thought of as being a 1.
E.G. 1-butene is the same as writing butene, etc...
