In summary, the conversation involves a discussion about the presence of a precipitate in the reaction between cyclohexene and sulfuric acid, as well as the solubility change observed. The results were yellow-orange initially but became murky. The individual is unsure of what to note for the solubility change. In contrast, in the reaction between toluene and sulfuric acid, only a color change was observed, and the solution remained clear. The individual is seeking clarification on how to describe the solubility change in this case. More specific details of the experiment are needed to provide a thorough explanation, such as if the experiment involves a reaction between cyclohexene and toluene, where cyclohexene can be proton

For cyclohexene and sulfuric acid reaction, is a precipitate suppose to form? the results looked yellow-orange ish, but it became murky. I'm suppose to note the solubility change, but i don't know what to say for it. Please help thanks.

For Toluene though, i heated it as well, and there was only a colour change, but it remained clear. What can I say about the solubility change for this? That it's still soluble? Again please help. Thanks

you'll need to be more specific and give out more details of the experiment, for instance, does this experiment involve a reaction between cyclohexene and toulene? In that case, cyclohexene could be protonated to become an electrophile which can react with toulene through an electrophilic aromatic substitution.

In the reaction between cyclohexene and sulfuric acid, a precipitate may form depending on the conditions of the reaction. The yellow-orange color and murky appearance suggest that a reaction has taken place and a product has formed. As for the solubility change, you can note that the product is less soluble in the reaction mixture compared to the starting materials.

As for the reaction between toluene and sulfuric acid, the color change indicates a reaction has occurred but the clear appearance suggests that no precipitate has formed. This could mean that the product is more soluble in the reaction mixture compared to the starting materials. However, more information about the conditions of the reaction and the specific products formed would be needed to accurately determine the solubility change.
 

What is the chemical equation for the reaction between cyclohexene and sulfuric acid?

The chemical equation for the reaction between cyclohexene and sulfuric acid is C6H10 + H2SO4 → C6H11HSO4.

What is the purpose of sulfuric acid in the reaction with toluene?

Sulfuric acid acts as a catalyst in the reaction with toluene, meaning it speeds up the reaction without being consumed in the process. It helps to break down the bonds in toluene and promotes the reaction with cyclohexene to form a new compound.

What are the products of the reaction between cyclohexene and toluene + sulfuric acid?

The products of this reaction are a mixture of toluene and cyclohexylsulfonic acid. The sulfuric acid adds a sulfonic acid group to the cyclohexene molecule, resulting in the formation of cyclohexylsulfonic acid.

Is the reaction between cyclohexene and toluene + sulfuric acid exothermic or endothermic?

The reaction between cyclohexene and toluene + sulfuric acid is exothermic, meaning it releases heat as a byproduct. This is due to the formation of new chemical bonds between the reactants, resulting in a more stable product.

What are the safety precautions when handling sulfuric acid in this reaction?

Sulfuric acid is a corrosive and toxic substance, so it should be handled with extreme caution. Always wear protective gear such as gloves, goggles, and a lab coat when handling sulfuric acid. It is also important to work in a well-ventilated area and avoid contact with skin or eyes. In case of accidental exposure, immediately rinse the affected area with water and seek medical attention.
