Answer:
See explanation
Explanation:
For this question, we have to remember the effect of an atom with high <u>electronegativity</u> as "Br". If the "Br" atom is closer to the carboxylic acid group (COOH) we will have an <u>inductive effect</u>. Due to the electronegativity of Br, the electrons of the C-H bond would be to the Br, then this bond would be <u>weaker</u> and the compound will be more acid (because is easier to produce the hydronium ion
).
With this in mind, for A in the last compound, we have <u>2 Br atoms</u> near to the acid carboxylic group, so, we will have a high inductive effect, then the C-H would be weaker and we will have <u>more acidity</u>. Then we will have the compound with only 1 Br atom and finally, the last compound would be the one without Br atoms.
In B, the difference between the molecules is the <u>position</u> of the "Br" atom in the molecule. If the Br atom is closer to the acid group we will have a <u>higher inductive effect</u> and more <u>acidity</u>.

To know the answer to this problem, you can search online or in any textbooks for the chemical formula of quinine. This is essential because you can detect from the chemical formula the number of hydrogen atoms.
Quinine has the chemical formula C₂₀H₂₄N₂O₂. So, the ratio of hydrogen to quinine is 24/1.
<em>Moles of hydrogen = 1.1 mol quinine * 24/1 = 26.4 mol</em>
