How many peaks are in the proton spin decoupled 13c nmr spectrum of 1,3,5-trinitrobenzene?

Natalka [10]

There are 2 peaks are in the proton spin decoupled 13C NMR spectrum of 1,3,5-trinitrobenzene .

The 13C NMR spectrum give the peak which is directly about the carbon skeleton not just the proton attached to it . The number of signals tell us how many different carbons or set of equivalent carbons . The splitting of a signal tells us how many hydrogens are attached to each carbon.

In 1,3,5-trinitrobenzene molecule , there are 2 peaks are in the proton spin decoupled 13C NMR spectrum three carbon give one signal and another three carbon give another one signal .

The mass of each WtWt isotope is measured relative to C−12C−12 and tabulated below. Use the mass of C−12C−12 to convert each of

Nadya [2.5K]

The question is incomplete , the complete question is;

The mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.

Wt-296 = 24.6622

Answer:

The atomic mass of Wt-296 is 195.9464 amu.

Explanation:

1 amu is defined as 1 by twelfth of the carbon-12 mass.

Mass of an isotope Wt-296 = 24.6622

Mass of an isotope Wt-296 in amu = M

$M\times \frac{1}{12 amu}=24.6622$

$M=24.6622\times 12 amu=295.9464 amu$

The atomic mass of Wt-296 is 195.9464 amu.
