Discussion Overview

The discussion centers around the correct IUPAC naming of two chemical compounds, specifically focusing on compound (b), which has a chiral center on C2. The scope includes nomenclature and the implications of chirality on naming conventions.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • Some participants propose that compound (a) should be named N-phenylhydroxylamine, while others suggest N-hydroxyaniline.
  • For compound (b), one participant believes it should be named 1,1-dichloro-2-ethylcycloheptane, while another participant notes that the presence of a chiral center on C2 will affect its IUPAC name based on the configuration of the ethyl group (R or S).
  • A participant requests the structures of compounds (a) and (b) to aid in determining the correct nomenclature.

Areas of Agreement / Disagreement

Participants express differing opinions on the correct names for both compounds, indicating that no consensus has been reached regarding the nomenclature of compound (b) due to the implications of chirality.

Contextual Notes

The discussion highlights the dependence on the specific arrangement of substituents around the chiral center, which is not fully resolved in the current exchanges.

Which one is the correct systematic name for compund (a), N-hydroxyaniline or N-phenylhydroxylamine ?

Also, how should we name compound (b), 2,2-dichloro-1-ethylcycloheptane or 1,1-dichloro-2-ethylcycloheptane ?

umm can you show the structure for a and b? haven't done nomenclature in awhile, but i should be able to figure it out pretty quick.
 
nevermind, had a brain fart.

i believe (a) is N-phenylhydroxylamine

and (b) is 1,1-dichloro-2-ethylcycloheptane
 
Thanks
 
no problem. however i should point out that (b) has a chiral center on C2, this will change it's IUPAC name depending on where the ethyl group is located (R or S).
