Answer:
The most appropriate structure given the sparse spectral data is<u><em> 4-acetyl benzoic acid (see attached).</em></u>
Explanation:
It is difficult to accurately elucidate the structure of this compound without its chemical formula. But from the 1H NMR spectral data shows a total of 8 hydrogen atoms:
- 12.71 (1H. s) - confirms presence of carboxylic acid proton, C=O-OH
- 8.04 (2H, d) - confirms aromatic hydrogen
- 7.30 (2H, d) - confirms aromatic hydrogen
- 2.41 (3H,s) - confirms C=C hydrogen or ketone O=C-RCH3
The attached files show the structure and the neighboring hydrogen atoms.

Answer:
Explanation:
Molarity refers to a measure of concentration.
Molarity = moles of solute/Litres of solution
Molarity refers to number of moles of solute present in this solution.
In order to find a solution's molarity, use value for the number of moles of solute and the total volume of the solution expressed in liters
As molarity of 2.3 mol of Kl is dissolved in 0.5 L of water,
Molarity =
