Alcohols
The major product formed when 2-methylpropan-2-ol is heated with concentrated H2SO4 at 443 K is:
Select the correct option:
Solution
2-Methylpropene
Tertiary alcohols undergo dehydration readily in acidic medium via E1 mechanism. 2-Methylpropan-2-ol forms a stable tert-butyl carbocation, followed by elimination to give the alkene. The major alkene product is 2-methylpropene.
