Hello again and thank you so much for your help. I attached the given IR and NMR for C6H12O. I really think it is 2-hexanone. Please, let me know if my answer is correct.
IR: c-h stretch less than 3000cm-1 and c=o stretch at 1720cm-1
H NMR:
triplet at 2.4ppm (d)
singlet at 2.1 (e)
quintet at 1.5 (c)
sextet at 1.2 (b)
triplet at 0.85 (a)
Thanks a lot
