Find the structure of unknown chemical

¹H NMR (400 MHz, CDCl₃) δ 0.95 (t, 9 H, J = 7.1 Hz), 2.61 (q, 6 H, J = 7.2 Hz).

Find the structure of unknown products for which you have the NMR spectrum (predicted).

Instructions

1. Select one exersise from the left table(click)

2. Analyse the spectrum and). Consider the chemical shifts, integrals(displayed on the top of each signal) and multiplicities.

3. Analyse the molecular formula of the target molecule (displayed over the spectrum viewer). Calculating the degree of unsaturation helps.

3. Draw your proposed structure in the JSME Molecular Editor.

4. The correctness of the solutions is evaluated each time that the structure is changed. If the rigth strucuture is drawn, the row of the table is inmediately highlighted in green.
