Statement I: The solvolysis of tert-butyl chloride is carried out in trifluoroethanol with a faster rate

Statement II: The solvent trifluoroethanol has higher ionizing power

Both statement I and statement II are correct and statement II is the correct explanation of statement I

The answer is (1) both statement I and statement II are correct and statement II is the correct explanation of statement I.

Statement I is correct because tert-butyl chloride undergoes solvolysis in trifluoroethanol at a faster rate. This is because trifluoroethanol is a more polar solvent than other solvents, such as water or ethanol. The increased polarity of trifluoroethanol makes it a better nucleophile, which facilitates the solvolysis reaction.

Statement II is also correct because trifluoroethanol has higher ionizing power than other solvents. This means that it is more likely to produce a carbocation intermediate, which is the rate-determining step in the solvolysis reaction.

The correct explanation for why statement I is correct is that statement II provides the reason for the increased rate. The increased polarity of trifluoroethanol makes it a better nucleophile, which facilitates the solvolysis reaction. The increased ionizing power of trifluoroethanol also makes it more likely to produce a carbocation intermediate, which is the rate-determining step in the solvolysis reaction.

Therefore, both statement I and statement II are correct and statement II is the correct explanation of statement I.

Here is a table that summarizes the properties of the solvents water, ethanol, and trifluoroethanol:

As you can see, trifluoroethanol is the most polar and has the highest ionizing power of the three solvents. This makes it the best solvent for the solvolysis of tert-butyl chloride.
