Organic Chem- acid catalyzed reation

AI Thread Summary
The discussion revolves around the major product of the acid-catalyzed hydration of 3-methyl-2-pentene. Participants debate whether the correct answer is 3-methyl-3-pentanol, citing the stability of tertiary carbocations. However, one participant argues against this, emphasizing the hierarchy of carbocation stability, which includes substituted allylic and other categories. The conversation highlights the complexity of carbocation stability and the need for precision in organic chemistry discussions. Ultimately, the topic underscores the importance of understanding reaction mechanisms and carbocation stability in predicting reaction outcomes.

Hey can anyone help me with this question?

What is the major product from the acid-catalyzed hydration of 3-methyl-2-pentene?

a. 3-methylpentane
b. 3-methyl-1-pentanol
c. 3-methyl-2-pentanol
d. 3-methyl-3-pentanol
e. 3-methoxypentane

Would the answer by D? My reasoning is that when that OH- group bonds to the third carbon, that carbon will be bonded to 4 substituents, which is very stable. Is this correct?
 
Physics news on Phys.org
the one rule to remember from all of O chem is the fact that tertiary carbocations are the most stable.
 
actually you are mistaken, tertiary carbocations are not the most stable

The order is as follows:

Substituded Allylic> 3 > Allylic > 2 >1 >Vinylic > Methyl
 
Well, if you really want to be specific you'd better include benzyllic, doubly allylic, doubly benzylic, triply allylic, triply benzyllic, cations stabilized by adjacent heteroatoms, non-classical carbocations, cations destabilized by inductive withdrawing groups, and on and on...
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
