A LITTLE CONFUSED...QUESTION ASKS THE REAGENT SHOWN IS ADDED TO THE COMPOUND, WHAT SHOULD YOU SEE WHEN THE TWO MATERIALS ARE MIXED TOGETHER? IS THE ANSWER THE PRODUCT OR THE REACTION, LIKE HEAT OR COLOR CHANGE. AND IF ITS PRODUCT IM CONFUSED? PLEASE HELP.
1.CH3-CH=CH-CH3 + H2SO4
2.CH3-CH=CH2 + BR2
(THE NUMBERS ARE SUBSCRIPT)
well obviously the product because it is asking what happends when they are mixed together. (that is your hint).
you take the reaction and from there combine them to make your product.
In this question, you are being asked what you would see when the reagent is added to the compound. To determine the answer, you need to consider the reaction that takes place when the two materials are mixed together.
Here are the reactions for the two given compounds:
1. CH3-CH=CH-CH3 + H2SO4: In this case, the compound CH3-CH=CH-CH3 (butene) reacts with H2SO4 (sulfuric acid). The reaction is an example of an acid-catalyzed hydration reaction. In this reaction, the double bond in the butene compound reacts with water (H2O) in the presence of sulfuric acid to form an alcohol. The product is CH3-CH(OH)-CH2-CH3 (2-butanol). So, when these two materials are mixed together, you would expect to see the formation of 2-butanol as the product.
2. CH3-CH=CH2 + Br2: In this case, the compound CH3-CH=CH2 (propene) reacts with Br2 (bromine). The reaction is an example of an addition reaction. In this reaction, the double bond in propene breaks, and the bromine atoms add to the molecule, resulting in the formation of 1,2-dibromopropane (CH3-CHBr-CHBr-CH3). So, when these two materials are mixed together, you would expect to see the color change from the reddish-brown color of bromine to a colorless solution as bromine adds to the propene, forming 1,2-dibromopropane.
In summary, when the reagents are added to the given compounds, you would expect to see the formation of specific products (2-butanol and 1,2-dibromopropane) or observable changes such as color changes in the mixture.
