Question

There are some compounds which are as follow:

1-hexene, 2-methyl-1-pentene, 2-hexene

Which of the following is the correct order for increasing order of reactivity for acid catalyzed hydration?

1)1-hexene<2-hexene<2-methyl-1-pentene

2)2-hexene<1-hexene<2-methyl-1-pentene

3)2-methyl-1-pentene<1-hexene<2-hexene

Answer 1

$\begin{array}{c}\text{As acid catalyzed hydration proceeds with carbocation}\\ \text{more the stability of carbocation greater the reactivity.}\end{array}$

$\text{So order is:}\text{1-hexene <}2\text{-hexene}<2\text{methyl-}1\text{-pentene}$
