Answer:

Option C. 2,2-dimethyl-1-propanol

Explanation:

The first attached picture, is the initial reactant.

Now, what happens in each step?, at first we have an alkyl bromide reacting with Mg/ether. This converts the reactant in a grignard reagent, which is often used in several ketones/ladehydes reactions, and even some acid and esthers.

Now, in the second step, we see this grignard reagent, reacting with CO₂ and H₃O⁺. At first, the grignard reagent will attach to the oxygen of the CO₂ by the MgBr, and the carbonated chain will attach to the carbonile. Then in acid medium, the OMGBr leaves the molecule, and form a carboxylic acid.

Finally, in the last step with LiAlH₄ and water, this compound just reduces the carboxylic acid to a primary alcohol, therefore, the only choice available is option c, 2,2-dimethyl-1-propanol.

See picture 2 below for the drawing.

How many moles are in 3.86 x 1023 molecules of Carbon Dioxide (CO2)?

Yuri [45]

Answer:

<h2>0.64 moles </h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L}$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{3.86 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{3.86}{6.02} \\ = 0.641196...$

We have the final answer as

<h3>0.64 moles</h3>

Hope this helps you

The growth of the plants that the animal used for food could not keep up with the needs of the population. there was so little f

WARRIOR [948]

In this case, the population has exceeded the available food, thus causing a decline in the population.

<h3>What is carrying capacity?</h3>

It is the maximum population size that an ecosystem can sustain based on the resources that it has.

Above the carrying capacity, resources become extremely limited and competition becomes stiff in the population. Thus, the population declines.

Below the carrying capacity, resources are abundant and the population grows. Most of the time, a mature population hovers around the carrying capacity of the ecosystem.

Ask Your Teacher You are given two clear, colorless aqueous solutions. You are told that one solution contains an ionic compound

Slav-nsk [51]

Answer:

Explanation:

Ionic compound are compounds formed by one atom losing an electron while the other gains electron as such the solution always contain charge ions compared to covalent solution which is predominantly formed by two atoms sharing electron. The two solution should be connected to a circuit with a bulb in turns with the same circuit, the solution that turns the bulb on is the ionic solution. This is because their charged ions conducts electricity when voltage is passed through it while the covalent solution does not conduct electricity.
