WebCarbocations. In the S N 1 mechanism, a tertiary carbocation is formed; This is not the case for S N 2 mechanisms as a primary carbocation would have been formed which is much less stable than tertiary carbocations; This has to do with the positive inductive effect of the alkyl groups attached to the carbon which is bonded to the halogen atom. The alkyl groups … Web8 Apr 2024 · Secondary alcohol needs about 100℃ in 75% H₂SO₄ and primary can only be dehydrated at 170℃ in 95% H₂SO₄ which are under extreme conditions. The dehydration process of both secondary and tertiary alcohols involves the formation of a product called the carbocation intermediate.

WebAs expected, tertiary carbocations are favored over secondary, primary and methyls. In general, primary and methyl carbocations do not proceed through the E1 pathway for this reason, unless there is a means of carbocation rearrangement to move the positive charge to a nearby carbon.
