Heating carvone with aqueous sulfuric acid converts it into carvacrol. The mechanism involves the following steps:

Chemistry
1 answer:
Fittoniya [83]3 years ago
5 0

Answer:

See figure 1

Explanation:

In this question, we have to start with the <u>protonation of the double bond</u>. In carvone we have two double bonds, so, we have to decide first which one would be protonated.

The problem states that the <u>terminal alkene</u> is the one that would is protonated. Therefore, we have to do the <u>protonation</u> in the double bond at the bottom to produce the <u>carbocation number 1</u>. Then, a hydride shift takes place to produce the <u>carbocation number 2</u>. A continuation, an <u>elimination reaction</u> takes place to produce the <u>conjugated diene</u>. Then the diene is protonated at the <u>carbonyl group</u> and with an elimination reaction of an hydrogen in the <u>alpha carbon</u> we can obtain <u>carvacol. </u>

I need help identifying the type of reactions. Can anyone help?
Eddi Din [679]

Answer:

Reaction 5: Decomposition reaction.

Reaction 6: Single replacement reaction

Reaction 7: Combination reaction.

Reaction 8: Combustion reaction.

Explanation:

<u><em>Reaction 5:</em></u>    2KClO₃ → 2KCl + 3O₂.

  • It is a decomposition reaction.
  • A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds.
  • In this reaction: potassium chlorate decomposes into two single components (potassium chloride and oxygen).
  • So, it is a decomposition reaction.

<u><em>Reaction 6:</em></u> Zn + 2HCl → H₂ + ZnCl₂.

  • It is a single replacement reaction.
  • A single-replacement reaction, a single-displacement reaction, is a reaction by which one (or more) element(s) replaces an/other element(s) in a compound.
  • It is most often occur if element is more reactive than the other, thus giving a more stable product.
  • In this reaction, zinc metal (more active) displaces the hydrogen to form hydrogen gas and zinc chloride, a salt. Zinc reacts quickly with the acid to form bubbles of hydrogen.

<u><em>Reaction 7:</em></u> N₂O₅ + H₂O → 2HNO₃.

  • It is a combination "synthesis" reaction.
  • A synthesis reaction has two or more reactants and only one product.
  • In this reaction, dinitrogen pentoxide reacts with water to produce nitric acid.
  • So, it is considered as a synthetic "combination" reaction.

<u><em>Reaction 8:</em></u> 2C₂H₆ + 7O₂ →  4CO₂ + 6H₂O.

  • It is a combustion reaction.
  • A combustion reaction is a reaction where hydrocarbon alkane is completely burned in oxygen to produce water and carbon dioxide.
  • In this reaction 1.0 mole of ethane is burned to give 4.0 moles of carbon dioxide and 6.0 moles of water.
  • So, it is considered as a combustion reaction.

PLEASEEEEEEEEEEEE HELPPPPPPPP I BEGGGGG FOR HELPPPPP
Elza [17]

Answer: There are 21.08\times 10^{23} molecules in 63.00 g of H_2O

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{63.00g}{18g/mol}=3.5moles

1 mole of H_2O contains =  6.023\times 10^{23} molecules

Thus 3.5 moles of H_2O contains =  \frac{6.023\times 10^{23}}{1}\times 3.5=21.08\times 10^{23} molecules.

There are 21.08\times 10^{23} molecules in 63.00 g of H_2O

What is the standard unit used to measure mass
AlladinOne [14]
The standard International System of Units (SI) unit of mass is the kilogram(kg). The kilogram is 1000 grams (g), first defined in 1795 as one cubic decimeter of water at the melting point of ice.

Draw the product of the reaction between CH3CH=CHCH3 and H2 under a platinum catalyst.
Pani-rosa [81]

Answer:

CH₃CH₂-CH₂CH₃

Explanation:

When an alkene, R-CH=CH-R reacts with H₂ in a Pt catalyst, the analogue alkane, R-CH₂-CH₂-R, is produced (Hydrogenation of alkenes via Pt/Pd catalyst)

Thus, the reaction of CH₃CH=CHCH₃ with H₂ under a platinum catalyst produce:

<h3>CH₃CH₂-CH₂CH₃</h3>

The analogue alkane
