The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement step by step. ### Step 1: Evaluate Statement-1 **Statement-1:** Carbocationic rearrangement is known as electrophilic rearrangement. **Analysis:** - Carbocationic rearrangement refers to the process where a carbocation (a positively charged carbon species) undergoes structural changes to achieve a more stable configuration. This can involve shifts such as hydride shifts or alkyl shifts. - Electrophilic rearrangement typically refers to reactions where an electrophile (a species that accepts an electron pair) is involved in the rearrangement. - While carbocation rearrangements do involve electrophilic species, the term "electrophilic rearrangement" is not commonly used to describe carbocation rearrangements specifically. **Conclusion:** Statement-1 is **incorrect**. ### Step 2: Evaluate Statement-2 **Statement-2:** Carbocations are stabilized by both hyperconjugation and +I effect. **Analysis:** - Carbocations are indeed stabilized by hyperconjugation, which involves the interaction of the empty p-orbital of the carbocation with adjacent C-H or C-C sigma bonds. This electron donation helps to disperse the positive charge. - The +I effect (positive inductive effect) refers to the electron-donating ability of alkyl groups. Alkyl groups can stabilize the positive charge on a carbocation by donating electron density through sigma bonds, reducing the overall positive charge density. - Both hyperconjugation and the +I effect contribute to the stability of carbocations. **Conclusion:** Statement-2 is **correct**. ### Final Conclusion - Statement-1 is incorrect. - Statement-2 is correct. Thus, the answer to the question is that Statement-1 is false and Statement-2 is true.
