Are the particles in a solid motionless ?

Chemistry
1 answer:
kifflom [539]3 years ago

No. Just because it is a solid doesn't mean it has no motion. The only way for particles to be motionless is for the solid to reach Absolute Zero (0* K). Which is impossible. So, therefore, it is impossible for particles in a solid to be motionless.

In your discussion consider a SN2 reaction mechanism concept. Propose a modification of experimental procedure that would improv
Hitman42 [59]

Answer:

Here's what I get  

Explanation:

You may have done a Williamson synthesis of guaifenesin by reacting guaiacol with 3-chloropropane-1,2-diol.

A. Mechanism

Step 1

NaOH converts guaiacol into a phenoxide ion.

Step 2

The phenoxide acts as the nucleophile in an SN2 reaction to displace the Cl from the alkyl halide.

B. Improve the yield

You probably carried out the reaction in ethanol solution — a polar protic solvent.

You might try doing the reaction in a polar aprotic solvent— perhaps DMSO.

A polar aprotic solvent does not hydrogen bond to nucleophiles, so they become stronger.

C. Another method of ether synthesis —dehydration of alcohols

Sulfuric acid catalyzes the conversion of primary alcohols to ethers.

This is also a nucleophilic displacement reaction.

Protonation of the OH converts it into a better leaving group.

Attack by a second molecule of alcohol forms the protonated ether.

A molecule of water then removes the proton.

worty [1.4K]
<h2>Question:</h2>

  • A solution that is able to dissolve additional solute is best described as _____.

<h2>Answer:</h2>

<h2>D.) Unsaturated </h2>

  • <u>Unsaturated</u> means the substance is poured into the solvent that can be dissolved. It is a solution (with less solute than the saturated solution) that completely dissolves, leaving with no remaining substances.

<h2>For example:</h2>

  • If you were to pour olive oil into a glass of water, it will dissolve, so it is <u>unsaturated</u>.

A carbon dioxide fire extinguisher is the best choice if an electric clothes dryer is on fire. Why would a water extinguisher no
valentina_108 [34]

An electrical fire would only be made worse by adding water. Using a CO2 extinguisher is smarter because it cools what ever has been set on fire making it less likely to light on fire again.
