Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism. The first step is the protonatio

n of alcohol and oxygen to form an oxonium ion.
Dehydration of 3-methyl-2-butanol forms one major and two minor organic products. Draw the structures, including hydrogen atoms, of the three organic products of this reaction.

Answer:

Most substituted alkene is produced as a major product

Explanation:

  • Dehydration of 3-methyl-2-butanol proceeds through E1 mechanism to form alkenes.
  • Most substituted alkene is produced as major product because of presence of highest number of hyperconjugative hydrogen atoms corresponding to the produced double bond (Saytzeff product).
  • Here, a H-shift also occurs in one of the intermediate step during dehydration to produce more stable tertiary carbocation.
  • Reaction mechanism has been shown below.

A student measures the mass of a sample as 9.64 g. Calculate the percentage error, given that the correct mass is 9.80 g.
rosijanka [135]

Answer:

<h3>The answer is 1.63 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual mass = 9.80 g

error = 9.80 - 9.64 = 0.16

We have

p(\%) =  \frac{0.16}{9.80}  \times 100 \\  = 1.632653061...

We have the final answer as

<h3>1.63 %</h3>

Hope this helps you

How many electrons are in an Fe2+ ion?<br> (1) 24 (3) 28<br> (2) 26 (4) 56
fomenos
The answer is (1) 24. There are 26 protons in nucleus of Fe atom. There is 26 electrons in Fe atom. Fe atom loses 2 electrons and change to Fe2+ ion. So there is 24 electrons in Fe2+ ion.

What is the balanced, net ionic equation
Effectus [21]

A net ionic equation which tends to show the ions that underwent a change in the reaction

<h3>What is a reaction equation?</h3>

The term reaction equation is the term that can be used to describe the instance where reactants combine together. If this occurs in solution we can say that the reaction is an aqueous phase reaction because the reactants wee all dissolved in solution.

It is possible for ionic substances in solution to react. When this occurs, it is possible for us to put down a net ionic equation which tends to show the ions that underwent a change in the reaction and the product of this reaction may be a liquid, a gas or a solid.

In this case, the complete molecular equation can be written as;

Ba(NO3)2(aq) + Na2SO4(aq) -----> BaSO4(s) + 2NaNO3(aq)

The complete ionic equation can be written as;

Ba^2+(aq) + 2NO3^-(aq) + 2Na^+(aq) + SO4^2-aq)  -----> BaSO4(s) +  2NO3^-(aq) + 2Na^+(aq)

Net ionic equation is;

Ba^2+(aq) + + SO4^2-aq)  -----> BaSO4(s)

How many moles is 1.50x10^23 molecules of NH3?
S_A_V [24]

 The   number  of moles that are  1.50  x10^23  molecules of NH3  are  

 =0.249 moles


       <u><em> calculation</em></u>

 The number of  moles is calculated  using  Avogadro's  law  constant

that  is  According  to Avogadro's  law

                         1  moles  of a  substance = 6.02 x10^23  molecules

                                    ?    moles                =  1.50  x10^23  molecules


by  cross  multiplication


= [( 1.50  x 10^23  molecules  x  1 moles) / (6.02 x10^23)]  = 0.249  moles
