Motohiro felt chilled by the rainy afternoon. He decided to make a cup of hot tea. He let the tea leaves steep too long and the
tea was bitter, Motohiro added some sugar to his tea to improve the flavor. After he stirred the sugar with the tea, he couldn’t see the sugar any longer.
Which statement best describes what happened to the sugar?
The sugar molecules disappeared.
The sugar molecules melted.
The atoms that make up the sugar were destroyed.
The sugar molecules mixed evenly with the tea
The sugar turned into a new substance.
(I don’t know the answer, my mouse is on a random one in the photo)
Thank you !

<span>The nitartion of methyl benzoate is expected to proceed as given in the equation below:
</span>
</span>
In methyl benzoate there are 3 types of 1 H proton. The two ortho to the C=O group is a doublet at 8 ppm the 2 metal to the C=O is a multiple at 7.5 ppm and one para to the C=O is a multiplet at 7.5 ppm.
On nitration the ortho will probably show two signal one being a single with 3 proton integration and one a doublet with 1 H integration
The meta will show a highly down field singlet (coresponding to 1 proton), two unequal doublets (corresponding to 1 H each) and one multiplets (corresponding to 1H). This is the major product as seen from the 1H NMR.
The para isomer will come as two doublets which will be very close to each other there is a small signal for this set between 8.2 and 8.3 ppm.
