Question
**Title: Ranking Carbocations by Stability** **Description:** In this exercise, you will rank the following carbocations from most stable to least stable. The stability of a carbocation is an important factor in determining the reactivity and the outcome of many organic reactions. **Carbocations:** - **Carbocation A:** A simple methyl carbocation with no alkyl groups attached. - **Carbocation B:** A secondary carbocation with one methyl group attached to the positively charged carbon atom. - **Carbocation C:** A tertiary carbocation with two methyl groups attached to the positively charged carbon atom. **Task:** Rank the carbocations from most stable to least stable based on their structural features. **Options:** - ○ A > C > B - ○ C > A > B - ○ A > B > C - ○ B > C > A - ○ B > A > C - ○ C > B > A **Explanation:** Consider the inductive and hyperconjugation effects of the alkyl groups. Tertiary carbocations are generally more stable than secondary, which are more stable than primary, due to electron-donating effects and greater hyperconjugation offered by alkyl groups.
