Answer:
The false statement is B.
Explanation:
When the temperature in a reaction increases, the rate of this reaction increases.
It means that it would be more probably to each molecule in the system collides but that does not mean that the reaction will happen faster because there is other factors that affect the velocity of the reaction, such as concentration of reactants, presence of catalyst, and activation energy.
Also, the nature itself of the reaction can affect the velocity, due to some of chemistry reactions occur instantaneously without increasing the temperature and in the case you increase the temperature the reaction will not occur quickly.
On the other hand, the size of the particle will affect the rate due to smaller particles are able to move faster than larger ones under high Temperature.
Answer:
Explanation:
Hello,
In this case, it is widely known that when measurements with different significant figures are put under mathematical operations, the final result must be displayed with the same amount of significant figures of the shortest measurement, thus, due to the fact that 5.5 g has two significant figures only the result is consequently shown with two significant figures as well as shown down below:
By rounding the first six to seven due to the fact that the next six is greater than five, according to rounding rules, the result is:
Best regards.
Here we have to draw the major product in the acid catalysed hydration reaction of 4-ethyl-3,3-dimethyl-1-hexene.
The 4-ethyl-3,3-dimethyl-1-hexene converts to 2-hydroxy-4-ethyl-3,3-dimethyl-1-hexane as a major product by acid catalyzed hydration reaction.
The acid catalyzed hydration of an alkene is the Sn¹ reaction. Where in the first step a carbocation is generated. The stability of the carbocation depends upon the position of the neighboring group having +I inductive effect.
In the next step the water molecule attack the carbocation and the corresponding alcohol is produced.
In 4-ethyl-3,3-dimethyl-1-hexene the carbocation formed in the C₂ position which is more stable than the C₁ position due to presence of the dimethyl and ethyl group in the neighboring position which have strong +I inductive effect. This is absence in C₁ position.
In the next step the water molecule attack the C₂ position to form the alcohol.
4-ethyl-3,3-dimethyl-1-hexene converts to 2-hydroxy-4-ethyl-3,3-dimethyl-1-hexane by acid catalyzed hydration reaction which is the major product along with 1-hydroxy-4-ethyl-3,3-dimethyl-1-hexane as a minor product.
The reaction mechanism is shown in the image.
