Among the given cations,……..is most stable (sec-bytyl carbonium ion, tert-butyl carbonium ion, n-butyl carbonium ion).

Text Solution

AI Generated Solution

To determine which cation is the most stable among the secondary butyl carbonium ion, tertiary butyl carbonium ion, and n-butyl carbonium ion, we can analyze the stability of each cation based on the concepts of hyperconjugation and inductive effects. ### Step-by-Step Solution: 1. **Identify the Cations**: - Secondary butyl carbonium ion (sec-butyl cation): This has the structure (CH3)2CH+. - Tertiary butyl carbonium ion (tert-butyl cation): This has the structure (CH3)3C+. - n-Butyl carbonium ion (n-butyl cation): This has the structure CH3(CH2)3C+. ...
