Answer 1

In the case of phenyl(3-phenyloxiran-2-yl)methanone:

FT-IR: epoxy:1280-1230 cm-1, carbonyl:1850, SP² C-H strech:3050-3150, SP² C-H bend: 650-1000, overtone patterns between 1660-2000, C=C: 1600-1480.

H¹-NMR: 8.1-8.0 (2 H, multiplate), 7.67 (1H, triple triplate or Multiplate), 7.58 (2H, multiplate), 7.41 (5H, Multiplate), 4.2 (1H, doublate), 4.16 (1H, doublate)

2. 2-hydroxy-1,3-diphenyl-3-(phenylamino)propan-1-one:

FT-IR (cm^-1):O-H: 3600-3500, N-H (2^o): 1 band between 3300-3500, C=O 1715-1810, SP² C-H bend: 650-1000, overtone patterns between 1660-2000, C=C: 1600-1480.

H¹-NMR:7.97 (2H, M), 7.53 (2H, M), 7.63 (1H, M), 7.40 (2H, M), 7.23 (5H, M), 6.73 (3H, Chirality), 5.34 (1H, M), 4.52 (1H, chirality)
