Answer to Problem 13.37AP

The cyclohexane gives only a single peak for all the hydrogens in the compounds while the $trans-2-hexene$ gives six signals in the NMR spectra. Both compounds are distinguished on the basis of the number of NMR signals.

Explanation of Solution

The compounds cyclohexane and $trans-2-hexene$ can be distinguished on the basis of NMR signals to be observed in the compound. Both of the compounds contain the same number of hydrogens.

Answer to Problem 13.37AP

The $tert−$ butyl methyl ether gives only two signals for all the hydrogens in the compounds while the isopropyl methyl ether gives three signals in the NMR spectra. Both compounds are distinguished on the basis of the number of NMR signals.

Explanation of Solution

The compounds $tert−$ butyl methyl ether and isopropyl methyl ether can be distinguished on the basis of NMR signals to be observed in the compound. Both of the compounds contain a different number of hydrogens. The NMR spectra of $tert−$ butyl methyl ether give only two signals due to the presence of two sets of protons. The isopropyl methyl ether gives three signals due to the presence of three sets of protons in the compound.

The only signal that is different in both the compounds is for the single hydrogen of methane group attached directly to the oxygen. Also, the splitting of the protons methyl groups into doublet occurs for isopropyl group while in $tert−$ butyl group all methyl groups give singlet peak.

Answer 12

Explanation of Solution

The compounds cyclohexane and $trans-2-hexene$ can be distinguished on the basis of NMR signals to be observed in the compound. Both of the compounds contain the same number of hydrogens. The NMR spectra of cyclohexane gives only one signal as all the hydrogens are equivalent in the compound. The $trans-2-hexene$ gives six signals due to the presence of six sets of protons in the compound.

The structure of $trans-2-hexene$ is given below along with six set of protons labeled alphabetically.

Interpretation Introduction

(b)

Interpretation:

An explanation as to how the compounds $trans-3-hexene$ and $1-hexene$ are distinguished using NMR spectra is to be stated.

Concept introduction:

Many nuclei and electrons have spin. Due to this spin magnetic moment arises. The energy of this magnetic moment depends on the orientation of the applied magnetic field. In NMR spectroscopy, every nucleus has a spin. There is an angular momentum related to the spin. The difference between its resonance frequency and that of the reference standard is known as the chemical shift of a nucleus. Tetramethylsilane (TMS) is taken as reference.
