Sn1 Reaction Lab Report
The effect of temperature on the reaction rate:
As the temperature increases it provides more kinetic energy to the molecules allowing them to move faster and with more energy the molecules can overcome the activation energy barrier and therefore the reaction occurs faster.
5. Since the proposed mechanism is a SN1 reaction the reaction got faster as the polarity increased. This is because SN1 reactions work best with polar protic solvents as they stabilize the carbocation. Therefore, as seen in the polarity chart in the data sheet Table 4, we can see that the 70:20 water and acetone ratio gives the fastest reaction as the more water there is the better, as water is polar protic and allows the reaction to occur faster.
6. When a different substrate was added there was no reaction seen in the given amount of lab time. This happened because as proposed earlier in question 3 the reaction mechanism is a SN1 reaction therefore, the reaction forms a carbocation in the process and the rate of the reaction or how fast the reaction will occur depends on the stability of the carbocation. In the case of SN1 reactions it prefers tertiary carbocation over secondary, and secondary over primary. Hence, the tBuCl had a …show more content…
The reaction that is occurring during the solvolysis of tBuCl is a SN1 reaction. This is based on the fact that the concentration of OH- remains constant while the concentration of tBuCl is changing as seen in Table 2. Also the change in concentration of OH- did not affect the rate of the reaction or reaction constant. The hydroxide has a rate order of zero and the t-butyl chloride has an order of, so overall rate order of 1. This is because the change in t-butyl chloride concentration did impact the reaction and the increase in concentration increased the reaction rate and the rate constant. In addition, in the t-butyl chloride structure the chlorine is attached to a tertiary carbon so the preferred reaction due to carbocation stability is also
