Question

For the following unknown, annotate the corresponding spetras and determine the molecular formula and lewis structure.

Unknown # s IR/HNMR/CNMR 1 MW= 88 AMU AVENUE

Answer 1

Hence, the molecular formula is 4 H₂O₂ > 100 cm 17ou can't 88 ppm 30 pm !! ~ 45ppm ć- CH₂ - 2.28 210 CH2 2.76 - CH₂ – OH 3.4 3.90 3200 cm ppm

- For given M. aut 0 IR spectre - 88 AMO a Peak at 3200 - 300 ml shows Presence of 0-H bond. b) peak at 1800 cmt confroms presence af carbonys (20) functional group © H NMR spectrum =) a) 2.2 ppm (S. 3H) ) corresponds to eu attached to the c-cu, b) 2.7 ppm CT2H) =) shoces presence oy -cm-c- 3.4 ppm (beads, 1H) = it is shoues presence of Ow moiety ds.9 ppm CT, 2H) =) it shows presence of cu - C2-0 linkage 6 3C NMR spoctrum =) a) 30ppm =) carbart of - Cuz go b) 45 ppm o cabon of cay-gp c) 18 ppm -) carbon af e-cu-o- 9P. d) 10 pom shows presence a ton ketone or aldehyde carbonyl group Bused on the can be above data structure of the compound Chyt- c- c4 - OH
