Trinitroaniline (TNA) has but one isomer (the long known 2,4,6-species) with a reported enthalpy of formation. Its positive DSE, and hence relative stabilization, is due to hydrogen... 

Amino-2,4,6-trinitrobenzene. It is designated in Ref 15a as TNA, which is a usual abbr for Trinitroaniline 12 =1,3-Diamino-... 

Trinitroaniline(2,4,5-TNA) It yel ndls, claimed to be prepd from 3-nitroacetanil-ide as described in Ref 2 According to Ref 3 this procedure yielded the 2,3,4,6-tetranitro-aniline instead of 2,4,5-TNA... 

Trinitroaniline (TNA) is an example of this group. Tetryl is not because both a nitro- and a methyl group are substituted on the amino nitrogen.
