An alkene on vigorous oxidation with ${\rm{KMn}}{{\rm{O}}_4}$ gives only acetic acid. The alkene is

${\rm{C}}{{\rm{H}}_3}{\rm{CH}} = {\rm{CHC}}{{\rm{H}}_3}$

${\rm{C}}{{\rm{H}}_3}{\rm{C}}{{\rm{H}}_2}{\rm{CH}} = {\rm{C}}{{\rm{H}}_2}$

${\left( {{\rm{C}}{{\rm{H}}_3}} \right)_2}{\rm{C}} = {\rm{C}}{{\rm{H}}_2}$

${\rm{C}}{{\rm{H}}_3}{\rm{CH}} = {\rm{C}}{{\rm{H}}_2}$

An alkene on vigorous oxidation with

\mathrm{KMn}{\mathrm{O}_4}

gives only acetic acid. The alkene is

View answer and explanation

Correct option: B

\mathrm{C}{\mathrm{H}_3}\mathrm{CH} = \mathrm{CHC}{\mathrm{H}_3}

Option B (

\mathrm{C}{\mathrm{H}_3}\mathrm{CH} = \mathrm{CHC}{\mathrm{H}_3}

) is correct because vigorous oxidation with

\mathrm{KMn}{\mathrm{O}_4}

yields only acetic acid.
