Answer:
The label of spectrum is attached.
Explanation:
adipic acid is equal to:
COOH - CH2 - CH2 - CH2 - CH2 - COOH
(1) (2) (3) (3) (2) (1)
The structure of adipic acid indicates that it has 3 equivalent carbons, therefore it should have 3 peaks in the spectrum:
The first peak at approximately 172 ppm is from carbon (1) COOH. The second peak is at approximately 23 ppm and is by carbon number (3) CH2. and the third peak is at approximately 37 ppm and is due to group number (2) CH2.
Answer:
90.71%
Explanation:
From the equation of reaction:
1 mole of salicylic acid requires 1 mole of methanol in order to produce 1 mole of methyl salicylate.
<em>mole = mass/molar mass</em>
1.6 g of salicylic acid = 1.6/138.121 = 0.012 moles
15 g of methanol = 15/32.04 = 0.47 moles
<em>Salicylic acid is the limiting reagent and hence, 0.012 moles of methyl salicylate would be produced according to the mole ratio above.</em>
0.012 moles of methyl salicylate = 0.012 x 152.1494 = 1.83 g
The theoretical yield of methyl salicylate is 1.83 g while the actual yield is 1.66 g.
<em>Percentage yield = actual yield/theoretical yield x 100%</em>
1.66/1.83 x 100% = 90.71%
