Organic Chemistry Practice Problem

[boatenbn]

I'm trying to find at least 3 constitutional isomers for CH3NO2 but I'm having trouble. Can someone help me come up with some isomers?

[John Cuthber]

What do you have so far?

[boatenbn]

So far, I've only come up with one. It looks something like this:

 

O

|

C-N-O

 

Is it acceptable for one of the structures to have two oxygens with formal charges of -1?

[Fuzzwood]

Don't stare yourself blind on the molecular formula. CH₃ doesn't have to indicate a methyl group, nor does NO₂ automatically mean a nitrogroup.

[For Prose]

Hint; think double bond from one of the oxygen atoms to something else
