Determine the number of different kinds of protons in each compounds
- 1-bromopropane (b) 2-bromopropane
- 2,2-dimethylpropane (d) 2,2-dimethylpentane
- (e) 1-chloro-4-methylbenzene (f) 1-chloro-2-methylbenzene
Short Answer
Step by step solution
1-bromopropane
In 1-bromopropane the three types of different hydrogens are present in proton NMR spectra.
They are marked as a, b, and c. So they will provide different proton NMR values.
(a)
2-bromopropane
In 2-bromopropane the two types of different hydrogens are present in proton NMR spectra.
They are marked as a, and b. So they will provide different proton NMR values.
(b)
2,2-dimethylpropane
In 2,2-dimethylpropane the one type of hydrogen is present in proton NMR spectra.
They are marked as a. So they will provide same proton NMR value.
(c)
2,2-dimethylpentane
In 2,2-dimethylpentane the four types of different hydrogens are present in proton NMR spectra.
They are marked as a, b, c and d. So they will provide different proton NMR values.
(d)
1-chloro-4-methylbenzene.
In 1-chloro-4-methylbenzene the three types of different hydrogens are present in proton NMR spectra.
They are marked as a, b, and c. So they will provide different proton NMR values.
(e)
1-chloro-2-methylbenzene
In 1-chloro-2-methylbenzene the four types of different hydrogens are present in proton NMR spectra.
They are marked as a, b, c and d. So they will provide different proton NMR values.
(f)
