A high pressure system is a whirling mass of cool, dry air that generally brings fair weather and light winds. High pressure weather tend to be free of clouds. Without clouds, there is no rain and hence the weather tends to be clear and fair.

High pressure occur where air sinks.

List the procedural steps, from start to finish, that are required to convert 2‑naphthol and allyl bromide into allyl 2‑naphthyl

elena-14-01-66 [18.8K]

<h3>Procedural steps are: - </h3>

On a small scale, the reaction is carried out by combining the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial.
To start the reaction, sodium hydoxide (base) is added.
To prevent solvent evaporation, the reaction flask is covered and stirred during the reaction.
TLC monitors the reaction's progress to ensure that no time is wasted.
To remove any remaining water, the reaction solution is dried over calcium chloride.
Column chromatography is used to purify the product, and evaporation is used to collect it.

<h3>What is Catalysis?</h3>

Catalysis is the process of boosting the pace of a chemical reaction by using a catalyst. Catalysts are not consumed in the reaction and so survive it.

In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions)

gregori [183]

Answer:

The correct answer will be " RbF > RbCl > RbBr > Rbl".

Explanation:

The size of the given ions will be:

⇒ 689kJ/mol

⇒ 660kJ/mol

⇒ 630kJ/mol

⇒ 785kJ/mol

Now according to the size, the arrangement will be:

⇒ (785kJ/mol) > (689kJ/mol) > (660kJ/mol) >(630kJ/mol)

⇒ RbF > RbCl > RbBr > Rbl

The bond among all opposite charging ions seems to be strongest whenever the ions were indeed small.

A sample of an unknown compound has a percent composition of 52.14% carbon, 13.13% hydrogen, and 34.73% oxygen. Which compounds

Artemon [7]

<h3>Answer:</h3>

The two possible compounds are;

1) Dimethyl Ether H₃C--O--CH₃

2) Ethanol H₃C--CH₂--OH

<h3>Solution:</h3>

Step 1: Calculate Moles of each Element;

Moles of C = %C ÷ At.Mass of C

Moles of C = 52.14 ÷ 12.01

Moles of C = 4.341 mol

Moles of H = %H ÷ At.Mass of H

Moles of H = 13.13 ÷ 1.01

Moles of H = 13.00 mol

Moles of O = %O ÷ At.Mass of O

Moles of O = 34.73 ÷ 16.0

Moles of O = 2.170 mol

Step 2: Find out mole ratio and simplify it;

C H O

4.341 13.00 2.170

4.341/2.170 13.00/2.170 2.170/2.170

2 5.99 1

2 6 1

Hence, Empirical Formula = C₂H₆O

<h3>Result:</h3>

As the molecular mass of compound is not given therefore, we can assume and guess the empirical formula to be the molecular formula. Hence, possible compounds are,

1) Dimethyl Ether H₃C--O--CH₃

2) Ethanol H₃C--CH₂--OH
