File:1,2 difluroethane ball and stick model.png

[edit]

Unused & opaque ball-and-stick model, hydrogen atoms are partly faded so they are transparent in some parts. Have File:1,2-Difluoroethane 3D ball.png as high-quality replacement. Chem Sim 2001 (talk) 19:49, 21 June 2019 (UTC)[reply]

  •  Keep for now. It matches the atom-color and conformation (syn) of File:1,2 Difluroethane Spacefill Model.png, whereas the proposed replacement is a different conformation (anti). In particular, conformational analysis (especially syn vs anti) of this specific chemical is a key part of en:Gauche effect (and related articles).
    I agree it has poor lighting (and the spacefill file I mentioned is even worse lighting). A unified set of [ball&stick and space-fill] of [syn and anti] in high quality and equivalent orientation (keeping one atom same and twisting other) could flip my vote to delete (and to also delete the others in the User:Mpiechowski set).

@DMacks: That's indeed a good reason for keeping the file for now. Yeah, my file is drawn in the anti-conformation. I try to upload a whole package of high-quality 1,2-Difluoroethane ball-and-stick as well as spacefill models in the future. Chem Sim 2001 (talk) 07:47, 22 June 2019 (UTC)[reply]
  •  Comment Is there a way to bring the filesize of the proposed replacement down a bit? It's 17MB whereas the nominated file is 55KB. The high quality ball&stick I see for other small compounds are typically in the few-hundred-KB range (example Category:1,2-dichloroethane generally have 1/100 your filesize but still manage to achieve 1/4 your pixels). Is there some way to bring that down without losing value? DMacks (talk) 03:40, 22 June 2019 (UTC)[reply]
@DMacks: You are right with this point as well! I have reduced the file size by compressing the file. Now they file size is about 200KB. Chem Sim 2001 (talk) 08:32, 22 June 2019 (UTC)[reply]

 I withdraw my nomination per reasoning of DMacks, I think we should keep the file for now until I or some other user uploaded a equivalent replacement with the same conformation. Chem Sim 2001 (talk) 08:32, 22 June 2019 (UTC)[reply]

Kept: withdrawn. --Christian Ferrer (talk) 15:10, 22 June 2019 (UTC)[reply]
