Assertion `(A)`: `SN^(1)` reaction is carried out in the presence of a plar protic solvent.
Reason `(R): A polar protic solvent increases the stability of carbocation due to solvation.

A

Both `(A)` and `(R)` are true and `(R0` is the correct explanation of `(A)`.

B

Both `(A)` and `(R)` are true but `(R)` is not the correct explanation of `(A)`.

C

`(A)` is true but `(R)` is false.

D

`(A)` is false but `(R)` is true.

The correct Answer is:
### Step-by-Step Text Solution 1. **Understanding SN1 Reaction**: - The SN1 (Substitution Nucleophilic Unimolecular) reaction is a two-step process where the rate-determining step involves the formation of a carbocation. - The first step involves the breaking of the bond between the alkyl group and the leaving group (like a halogen), resulting in the formation of a carbocation and a leaving group. 2. **Role of Polar Protic Solvent**: - Polar protic solvents, such as water or alcohols, can stabilize the carbocation formed in the first step of the SN1 reaction. - These solvents have hydrogen atoms that can participate in hydrogen bonding and solvation, effectively surrounding and stabilizing the positively charged carbocation. 3. **Assertion Evaluation**: - The assertion states that "SN1 reaction is carried out in the presence of a polar protic solvent." This is true because polar protic solvents are commonly used in SN1 reactions to stabilize the carbocation intermediate. 4. **Reason Evaluation**: - The reason states that "A polar protic solvent increases the stability of carbocation due to solvation." This is also true. The solvation process helps to stabilize the carbocation by surrounding it with solvent molecules, thus lowering its energy and making it more favorable for the reaction to proceed. 5. **Conclusion**: - Since both the assertion and the reason are correct, and the reason provides a correct explanation for the assertion, we conclude that both statements are true and related. ### Final Answer: Both the assertion and reason are correct, and the reason is the correct explanation of the assertion.
