Question:
Draw a compound that is consistent with the following ^3H NMR data:
a. C_4H_9Br, has 3 signals in the ^1H NMR spectrum, 2 doublets and a 9-line multiplet.
b. C_4H_9Br_2, has 3 signals in ^1H NMR spectrum, a singlet, a triplet and a quartet.
Give the structure of a compound with a formula of C_4H_10O_2 that gives only two singlets in the ^1H NMR spectrum in an integral ratio of 3:2.
HNMR Spectroscopy:
NMR is widely used in elucidation of chemical structures. Proton NMR or H NMR is sensitive to the hydrogen nuclei in a substance which is why it is a good option for analysis of hydrogen-containing organic compounds.
Answer and Explanation:
a. {eq}C_4H_9Br {/eq}
 |
Hydrogen atoms encircled yellow will give a doublet, green has a 9-line multiplet and blue has a doublet.
b. {eq}C_4H_8Br_2 {/eq}
 |
The hydrogen atoms encircled blue is an NMR singlet, yellow is a quartet, and green is a triplet.
c. {eq}C_4H_{10}O_2 {/eq}
 |
The hydrogen atoms encircled blue and green give an integral ratio of 3:2.
