318040 When subjected to acid catalysed hydration, the order of reactivity of the alkenes is;
I. \(\left(\mathrm{CH}_{3}\right)_{2} \mathrm{C}=\mathrm{CH}_{2}\),
II. \(\mathrm{CH}_{3} \mathrm{CH}=\mathrm{CH}_{2}\) and
III. \(\mathrm{CH}_{2}=\mathrm{CH}_{2}\) is

1 III \(>\) II \(>\) I

2 I \(>\) III \(>\) II

3 I \(>\) II \(>\) III

4 II \(>\) I \(>\) III

Explanation:

Acid catalysed hydration of alkenes involve formation of carbocation intermediate. Higher
the stability of carbocation intermediate, more
is the reactivity towards acid
catalysed hydration.
The order of stability of carbocation (formed) is
\({\left( {{\rm{C}}{{\rm{H}}_{\rm{3}}}} \right)_{\rm{2}}}\mathop {{\rm{CC}}}\limits^{\rm{ + }} {{\rm{H}}_{\rm{3}}} > {\rm{C}}{{\rm{H}}_{\rm{3}}}\mathop {{\rm{CH}}}\limits^{\rm{ + }} {\rm{C}}{{\rm{H}}_{\rm{3}}} > \mathop {\rm{C}}\limits^{\rm{ + }} {{\rm{H}}_{\rm{2}}} - {\rm{C}}{{\rm{H}}_{\rm{3}}}\)
Thus, the order of reactivity towards acid catalysed hydration is
\[\begin{array}{*{20}{l}}

Explanation:

Acid catalysed hydration of alkenes involve formation of carbocation intermediate. Higher
the stability of carbocation intermediate, more
is the reactivity towards acid
catalysed hydration.
The order of stability of carbocation (formed) is

Explanation:

Acid catalysed hydration of alkenes involve formation of carbocation intermediate. Higher
the stability of carbocation intermediate, more
is the reactivity towards acid

The order of stability of carbocation (formed) is
