Draw the Zaitsev product formed when 2,3‑dimethylpentan‑3‑ol undergoes an E1 dehydration. The starting material is a chiral carb

on with an in plane bond pointing up to methyl and an in plane bond to O H pointing to the lower right. There is a wedged bond to isopropyl pointing to the lower left and a dashed bond to ethyl pointing to the left. This reacts with H 3 P O 4 in an E 1 reaction to give the Zaitsev product.

Answer:

See explanation

Explanation:

Dehydration of an alcohol by E1 mechanism occurs in two steps. The first step is the is the protonation of the -OH group in the alcohol followed by the elimination of water, a good leaving group.

In the case of  2,3‑dimethylpentan‑3‑ol, the carbocation formed undergoes rearrangement followed by loss of a hydrogen atom. This now yields the product as shown in the image attached.

Note that, the Zaitsev's product is the most substituted product and is most stable hence it is the most favored product.

The concentration of hydroxide ions is less than the concentration of hydronium ions for acidic solutions. True False
wolverine [178]

Answer:

True

Explanation:

It's true because the pH is a measure of how basic or acid a solution is. In an acidic medium, the pH scales goes from 0 to 7. While in a basic medium goes from 7 to 14. The lower the pH value of the most acid the solution is.

1. The expression pH = -log(molar concentration of hydronium) allow to calculate the pH of a solution.

2. On the other hand, the expression pOH = -log(molar concentration of hydroxide) allow to determine the pOH of a solution.

The values of pH and pOH always obey the following expression:

pH + pOH = 14

Thus if for instance the pH becomes smaller the pOH must become bigger in order to fulfill the equation. Which means that the concentration of hydronium ions is greater than the hydroxide concentration.

For example, in an acidic medium:

if pH= 3, pOH= 11

In this case the molar concentration of hydronium is 0,001M. And the molar concentration of hydroxide ions is just 0,00000000001M.

Identify whether each species functions as a Brønsted-Lowry acid or a Brønsted-Lowry base in this net ionic equation.CH3COO-+HCO
NARA [144]

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor

The given equilibrium reaction is,

CH_3COO^-+HCO_3^-\rightleftharpoons CH_3COOH+CO_3^{2-}

In this reaction, CH_3COO^- and HCO_3^- are act as Bronsted Lowry base and acid respectively and CH_3COOH and CO_3^{2-} are act as Bronsted Lowry acid and base respectively.

The formula of conjugate of CH_3COO^- is, CH_3COOH

The formula of conjugate of HCO_3^- is, CO_3^{2-}

Mg(s) + 2 HCl (aq) _MGCL2 (Aq) + H2 (g) the total pressure of gas collected over water is 740.0 mmhg and the temperature is 21.5
Julli [10]

The pressure of hydrogen gas formed  is 720.8 mmHg.

<h3>What is Partial Pressure ?</h3>

The pressure exerted by a (specified) component in a mixture of gases.

We have to understand one thing that the Hydrogen, which is collected over water, will be mixed with water vapor.

This means that the total pressure of the mixture will have two components.

  • the partial pressure of Hydrogen
  • the vapor pressure of water at 21.5 C

The vapor pressure of water at that temperature is approximately

19.231 mmHg.

This means that

\rm P_{total} = P_{hydrogen}  + \; P_{water vapor}

740 = \rm P_{hydrogen} + 19.231

\rm P_{hydrogen} = 740-19.231

\rm P_{hydrogen} = 720.8 mmHg

Therefore the pressure of hydrogen gas formed  is 720.8 mmHg.

Upon decomposition, one sample of magnesium fluoride produced 0.764 kg of magnesium and 1.19 kg of fluorine. A second sample has
miskamm [114]

Answer:

3.50 kg

Explanation:

Law of definite proportion: These law states that all pure samples of a particular chemical compound contains similar elements combined in the same proportion by mass.

From the law above,

First sample,

The ratio of fluorine and magnesium in the sample of magnesium fluoride is

0.764:1.19 = 1:1.6

mass of fluorine: mass of magnesium ≈ 1:1.6

Second sample,

mass of magnesium fluoride = 5.75 kg

mass of magnesium = 1.19(5.75)/(1.19+0.764)

mass of magnesium = 6.8425/1.954

mass of magnesium = 3.50 kg

Hence the second sample produced 3.50 kg of magnesium.
