Question

Shown above is the ¹H-NMR spectrum of a compound with the formula C5H10O2 . Choose from the constitutional isomers below to assign a structure to this spectrum.

3H 2H 3H 2H PPM Shown above is the 'H-NMR spectrum of a compound with the formula C5Hi002. Choose from the constitutional isomers below to assign a structure to this spectrum a b C CH3CH2CH2CH2COH CH3CH2COCH2CH3 CH3CH2CH2COCH3 (Choose the letter corresponding to the correct structure from the drop-down list provided.) Correct Structure: Assign signal number 1 (indicated as a red number on the spectrum above) to its corresponding hydrogen(s) (shown as a red lower-case letter on the structure above) (Write the letter of the hydrogen (or set of equivalent hydrogens) in the box provided, e.g., a) Signal number 1 corresponds to hydrogen(s) Prev

Answer 1

Correct structure = C

Peak 1=d

2=c
