Predict the product of the following Wittig reaction: You may want to draw out the reaction of a separate piece of paper before submitting your response. 2-butanone reacts with (C2H5O)2P=O--CHC.Hs with added heat in a potassium salt solution
a) Potassium diethyl phosphate
b) (z)-stilbene
c) 2-methylbut-1-enyl-benzene
d) 2-methylbutene diethyl phosphate

Answers

Answer:

c) 2-methylbut-1-enyl-benzene

Explanation:

From the information given:

Wittig reaction is essential for the creation of carbon-carbon bonds which results in the production of alkenes. The presence of the ketone compound ( 2-butanone) is because of its high electrophilic character of the carbonyl carbon. The reaction between 2-butanone with triethylamine in the presence of potassium salt is to catalyze the reaction. This reaction proceeds to yield the product 2-methylbut-1-enyl-benzene.

when comparing ethanol and acetic acid, which one has the most polar bond? and what is that bond?​

Answers

Answer:

Ethanol is another alcohol, and since there are less carbons in its chain, it will be more polar. So Ethanol is the most polar bond, it has two different types of bonding between its constituent atoms. The bonds between the hydrogen and carbon atoms are nonpolar covalent bonds. The hydrogen-oxygen and carbon-oxygen bonds are polar covalent bonds.

When ice melts, liquid water performs the act of erosion by carrying away the tiny rock fragments lost in the split. This specific process (the freeze-thaw cycle) is called frost weathering or cryofracturing. Temperature changes can also contribute to mechanical weathering in a process called thermal stress.

Which materials allow electrons to flow through them?
A. Insulators only
B. Semiconductors and conductors
C. Conductors only
D. Semiconductors and insulators

Answers

The materials which allow electrons to flow through them are Semiconductors and conductors. Hence Option (B) is correct.

What are conductors ?

A conductor, or electrical conductor, is a substance or material that allows electricity to flow through it.

In a conductor, electrical charge carriers, usually electrons or ions, move easily from atom to atom when voltage is applied.

Therefore, The materials which allow electrons to flow through them are Semiconductors and conductors. Hence Option (B) is correct.

1. At an environmental testing lab, a lab technician calculated the known concentration of the calibrating solution three times too high. How will this affect the results of the samples run using this calibration solution

Answers

Answer:

The deviation in the results will be too large when compared with the actual result

Explanation:

The effect this will have on the results of the samples run using this Calibration solution is that the deviation in the results will be too large when compared with the actual result that was supposed to be obtained. and this will also lead to wrong analysis by the technician .

This will cause a result that is very different from the actual result, which will lead to errors in the analysis.

We can arrive at this answer because:

A laboratory test must be done accurately and all calibrations must follow the test protocol.Changing the calibration will cause inaccurate and incorrect results, which differ from the actual result.This will promote an analysis that is unreal, false, and far from true, which will leave the entire test inaccurate.

As we can see from the question above, the lab technician used a much higher calibration than what was recommended in the lab. This will lead to inaccurate and incorrect results.

Answers

Answer:

A liquid that evaporates rapidly at low temperatures

Answer:

A liquid that evaporates rapidly at low temperatures.

Explanation:

A volatile liquid such as gasoline evaporates easily. Its chemicals aren't held together as strongly, and room temperature is often enough to break intermolecular bonds and evaporate them.
