A) overall, the process results in syn addition and Markovnikov orientation
B) overall, the process results in anti addition and Markovnikov orientation
C) overall, the process results in syn addition and anti-Markovnikov orientation
D) overall, the process results in anti addition and anti Markvnikov orientation.

Answers

Answer 1

The statement that is true for the formation of the alcohols by hydroboration-oxidation sequence is C) overall, the process results in syn addition and anti-Markovnikov orientation.

The hydroboration oxidation is the chemical reaction in the alkenes are converted in to the alcohols. this is the two steps process , the step steps includes the hydroboration and the other steps includes the oxidation. The conversion of the alkenes in to the alcohols is done by the anti markovnikov reaction. it is result of the net addition of the water.

Thus , the hydroboration oxidation done by the syn addition and the anti markovnikov orientation.

When a physical change in a sample occurs, composition of sample does not change.

What are physical changes?

Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.

Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.

They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

Cd²+(aq) + 2e¯→→Cd(s)              E° = -0.40V

So, the cell potential is calculated as follows:

E° cell = E° cathode - E°anode

For the reaction to be spontaneous, the E should be postive, thatis cell

Thus, E°cathode-E°anode>0

E° cathode > E° anode

So, the value of volatic  cell potential will be more for the cathode.

Here, the E° is more for Ag+ (aq) | Ag(s) and less for Cd2+ (aq) |Cd(s). Therefore, Ag* (aq)| Ag(s) acts as a cathode and Cd²+ (aq) | Cd(s)

What are Bronsted-Lowry acids?

Bronsted-Lowry acids are substances that donate a proton in a reaction.

When Bronsted-Lowry acids donate protons, the substance formed is called a conjugate base. The conjugate base is able to accept a proton to form the Bronsted-Lowry acid.

For weak acids, dissociation into ions is not complete. Hence, the strength of weak acids is given by their acid dissociation constant, Ka.

The higher the Ka value of an acid, the stronger will be the acid.

The distribution coefficient is a measure of how well a compound dissolves in one solvent relative to another. In this case, the distribution coefficient of caffeine in chloroform and water is 10, which means that caffeine is 10 times more soluble in chloroform than it is in water.

If the goal is to extract 90% of the caffeine present in one extraction, this means that 90% of the caffeine must be dissolved in the chloroform, while only 10% remains in the water. Since the distribution coefficient is 10, this means that the relative volume of chloroform-water must be 10 times larger than the relative volume of water.

In other words, if the relative volume of water is Vo/Vaq, the relative volume of chloroform-water must be 10 * (Vo/Vaq) in order to extract 90% of the caffeine. Therefore, the relative volume of chloroform-water that must be used is 10 * (Vo/Vaq) = 90% of the caffeine.

Answers

What can be concluded from the table is that the reaction occurs more quickly when the concentration of salt is higher. Option B.

Reaction rates

In chemistry, the rate of reaction is the time it takes for the reactants of a reaction to become products. It can also be defined as the rate of the disappearance of reactants or the rate of appearance of products of a reaction.

In this case, the reaction we are talking about is the rotting of a rope. From the available data on the table, it took the rope 10 years to rot in lake water while it took the same rope 4 years to rot in ocean water.

Assuming that all other factors are kept constant, the only difference between the lake water and the ocean water is that while the lake water contains almost zero salt, the concentration of salt in the ocean water is high.

Thus, one can logically conclude that the rate of rotting of the rope is quickened by the presence of high salt concentration in the ocean water.

Answers

The statement that is true regarding the solution prepared by adding 0.10 mol of potassium acetate to 1.00 L of water is that it is acidic (option B).

How to calculate pH?

pH refers to the measure of the acidity or alkalinity of a solution. It can be calculated by using the following expression:

pH = - log {H}

Where;

H = hydrogen ion concentration

The concentration of the acetate solution must first be calculated by dividing the number of moles by its volume as follows:

Molarity = no of moles ÷ volume

Molarity = 0.10 mol ÷ 1L = 0.1M

pH = - log {0.1}

Answers

The temperature at which the gas could have zero volume is called absolute zero. It is a hypothetical condition where all the curves meet at a point at V= 0 and T becomes -273.15°C.

The plot of the volume of a sample of gas versus temperature at three different pressures is a graphical representation of the ideal gas law.

As the temperature of the gas sample increases, the pressure increases, and the volume of the gas sample increases as well.

However, the rate at which the volume of the gas sample increases is different at the three different pressures. At higher pressures, the volume increases more quickly than at lower pressures, indicating that the gas sample is more compressible at higher pressures.

This can be seen in the plot as the curves for the three different pressures diverge. Additionally, the plot also shows that the volume of the gas sample increases more quickly at higher temperatures.

This is because the kinetic energy of the gas molecules increases with temperature, allowing them to move more freely, thus increasing the volume of the gas sample.

Hydrogen bonding is a type of intermolecular bonding that occurs between hydrogen atoms that are bonded to strongly electronegative elements like oxygen, chlorine, fluorine, and nitrogen.

Due to the stronger attraction of the electronegative elements to the shared electron pair, the electronegative element acquires a partial negative charge while the hydrogen atom acquires a partial negative charge. This uneven charge distribution results in the atoms of hydrogen being attracted to the atoms of the electronegative elements of neighboring molecules, thus producing hydrogen bonding.

C atom that is attached to four different atoms or groups or having any symmetry elements can be called a chiral compound if not it is achiral.

Organic compounds that have one C atom with four different atoms attached, rotate plane polarised light, and have a symmetry element like a plane of symmetry, line of symmetry, or centre of symmetry are known as chiral compounds, whereas compounds without any symmetry element are known as achiral compounds. Light with a plane polarization is not rotated.

The image below shows the trichloro derivative of cyclobutane and cyclopentane, in which the molecules containing the C atom with the symbol * are chiral while the remaining molecules are achiral.
