Which of the following represent the correct increasing order of unsaturation?
Alkanes < Alkenes < Alkynes
Alkanes < Alkynes < Alkenes
Alkenes < Alkynes < Alkenes
Alkynes < Alkanes < Alkenes
Alkanes are saturated hydrocarbons. Alkenes and alkynes are unsaturated hydrocarbons. So, increasing order of unsaturation is Alkanes, Alkenes and Alkynes.
