Problem- a 1h nmr signal is observed at 2060 hz downfield


Problem- A 1H NMR signal is observed at 206.0 Hz (downfield of TMS) on a 125-MHz instrument.

a) What is the observed chemical shift in parts per million (ppm)?

b) What is the chemical shift, in parts per million (ppm), if the sample is analyzed with a 300.0-MHz instrument?

c) Where will the proton signal appear, in hertz, if the sample is analyzed with a 300.0-MHz instrument?

This is the question for that you have to provide expert solution
