Question

d,e,3,4 please

d) The suggested transition state geometry for the rate-determining step of free-radical chlorination (compared to that for bromination process of alkanes is (circle your choice) A Late/An Early occurring one. It is more (circle your choice) Reactant-Like / Product Like. e) Given the rigid structure shown below, 3. How many peaks do you predict to observe on "H-NMR spectrum of this compound? 4. How many peaks do you predict to observe on 13C-NMR spectrum of this compound?

Answer 1

1H NMR spectrum- 4 peaks

Total 8 hydrogens are there, but 4 hydrogens will be enantiomeric to the other 4 hydrogens as the molecule contains a plane of symmetry. So 4 peaks will be seen in 1H spectrum.

13C NMR- total 4 peaks will be there. 3 of the cyclohexene ring carbon are enantiomeric to the other 3 carbon of the ring, so they will show 3 peaks, and the another peak comes from the ester carbonyl carbon.
