Answer 1

Answer #1

SOLN 1

1->4 is carried out by using H2/Pd as reducing agent

a. Spectra C is of 4th molecule since it has two signal which will correspond to CH2 and CH3 group

b. Spectra D is of 1st molecule since it has 4 signal which will correspond to CH2 , CH3 , CH and terminal CH2 group

c. spectra B is of 2nd molecule since its one CH3 of two OEt group , similarly 1 signal for CH2 of OEt , one for CH and one for CH3 of main chain

d. Lastly spectra A is of 3rd molecule

need help drawing the structures for each For each pair of spectra, first calculate the THD for the molecular formula. Then draw a structure which matches all features of both spectra (there may be more than one structure which fits). For partial credit, write out individual spectral interpretations on each spectrum, noting either presence (or absence) of FG's or bond types. Remember your calculated IHD!! (6 points each) 1.
