Hi:) anyone able to explain the last column? Thanks !!
RUDIKE [14]

I'll try to explain this in the simplest way I've learned it.

What the last column basically meant was that if the second word of the compound has a negative ion charge

and contains oxygen it will give the the compound a name ending with -ate

VladimirAG [237]

Answer:

The chemical shift (δ) for CHBr₃ proton = <u>6.88 ppm</u>

Explanation:

In NMR spectroscopy, Chemical shift (δ) is expressed in parts per million (ppm) and is given by the equation:

\delta (ppm)= \frac{Observed\: frequency, \nu (Hz)}{Frequency\: of\: Spectrometer, \nu^{'} (MHz)}\times 10^{6}                     ....equation (1)

Given: Observed frequency: ν₁ = 2065 Hz,

Spectrometer frequency: ν'₁ = 300 MHz, ν'₂ = 200 MHz

To calculate the chemical shift (δ) for the given CHBr₃ proton, we use the equation (1)

\delta = \frac{\nu_{1} (Hz)}{\nu_{1}^{'} (MHz)}\times 10^{6} = \frac{2065 Hz}{300 \times 10^{6} Hz}\times 10^{6} = 6.88 ppm

Since in NMR spectroscopy, chemical shift is a <em>field independent scaling</em>. Thus the value of the chemical shift of a given proton, such as CHBr₃ proton, is <u><em>independent of the magnetic field strength of the spectrometer.</em></u>

<u>So the value of chemical shift of a given proton remains same when measured with a 300 MHz and 200 MHz NMR spectrometer.</u>

<u>Therefore, the chemical shift (δ) for CHBr₃ proton = 6.88 ppm</u>
