Anwer: the first option, a hydrogen ion acceptor.

The acid-base model of Bronsted-Lowry is focused on hydrogen ion. An acid is a donor of hydrogen ions and a base is a receptor of hydrogen ions.

\boxed{{\text{A hydrogen ion accept or}}} describes a Bronsted-Lowry base.

Further Explanation:

Different theories have definitions of acids and bases. These theories are as follows:

1. Arrhenius theory: According to this theory, acid produces hydrogen or hydronium ions in a solution, while the base produces hydroxide ions in a solution. HCl, {\text{HN}}{{\text{O}}_3} and  {{\text{H}}_2}{\text{S}}{{\text{O}}_4} are Arrhenius acids while NaOH and KOH are the examples of Arrhenius bases.

2. Bronsted-Lowry theory: This theory defines acid as the proton or hydrogen ion donor and base as the proton or hydrogen ion acceptor. {{\text{H}}_2}{\text{O}} acts as Bronsted acid while {\text{N}}{{\text{H}}_3} is a Bronsted base.

3. Lewis theory: According to this theory, an acid accepts a pair of electrons from electron-rich species while a base donates electrons to electron-deficient species in the reaction. Examples of Lewis acids are {\text{B}}{{\text{F}}_3}, {\text{S}}{{\text{O}}_3} while {{\text{H}}_2}{\text{O}} and ROH are the examples of Lewis base.

A hydrogen ion acceptor

According to Bronsted-Lowry theory, Bronsted-Lowry base is the species that accepts protons or hydrogen ions. So this is incorrect.

An electron pair donor

A compound that donates an electron pair act as Lewis base, not Bronsted-Lowry base. So this is incorrect.

An electron pair acceptor

A compound that accepts an electron pair act as Lewis acid, not Bronsted-Lowry base. So this is incorrect.

A hydrogen ion donor

According to Bronsted-Lowry theory, the species that donates protons or hydrogen ions is known as Bronsted-Lowry acid, not base. So this is incorrect

Which acid could not be prepared by treating a Grignard reagent with CO2?
Anni [7]

Answer:

4-oxopentanoic acid.

Explanation:

In this case, we must remember that the Grignard reaction is a reaction in which <u>carbanions</u> are produced. Carboanions have the ability to react with CO2 to generate a new C-C bond and a carboxylate ion. Finally, the acid medium will protonate the carboxylate to produce the <u>carboxylic acid group. </u>

The molecules that can follow the mechanism described above are the molecules: p-methylbenzoic acid, cyclopentane carboxylic acid and 3-methylbutanoic acid. (See figure 1)

In the case of <u>4-oxopentanoic acid</u>, the possible carbanion <u>will attack the carbonyl group</u> to generate a cyclic structure and an alcohol group (1-methylcyclopropan-1-ol). Therefore, this molecule cannot be produced by this reaction. (See figure 2)

devlian [24]
If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase. However, if you were to maintain a constant volume while decreasing pressure, the temperature would also have to decrease.

A buffer solution is made using a weak acid, HA. If the pH of the buffer is 9 and the ratio of A– to HA is 100, what is the pKa
sdas [7]
To calculate the pKa of the weak acid, we use the Henderson-Hasselbalch equation. It is expressed as pH = pKa - log [HA]/[A-]. This equation takes into account the concentration of the substance that does not dissociates into ions since it is a weak acid. We caculate as follows:

pH = pKa - log [HA]/[A-]
9 = pKa - log 1/100
pKa = 7
