Which is most stable N-butyl sec-butyl t-butyl?

Answer 1

If u are referring to the carbocations of n-butyl, sec-butyl, and t-butyl, the most stable is the one that has the most alkyl groups attached to the positively charged carbon atom. In this case:

- n-butyl has only 1 alkyl group attached

- sec-butyl has 2 alkyl groups attached

- t-butyl has 3 alkyl groups attached

Therefore, t-butyl is the most stable carbocation

Answer 2

T-butyl is the most stable due to having three equivalent methyl groups around a central carbon, leading to steric hindrance that lowers reactivity. Next is sec-butyl with bulky groups at one end of the chain causing some steric hindrance. Lastly, n-butyl lacks the steric hindrance present in the other two structures, making it the least stable.
