Sticky Note
Generally the decreasing order of reactivity is?
  1. Alkane > Alkynes > Alkene
  2. Alkene > Alkynes > Alkanes
  3. Alkane < Alkynes > Alkene
  4. Alkene < Alkynes < Alkanes
Explanation

The correct decreasing order of reactivity is Alkene > Alkynes > Alkanes. 

Alkynes:

  • These have the most reactive π bonds due to the triple bond between carbon atoms, making them susceptible to a wide range of reactions. 

Alkenes:

  • They have one π bond, making them less reactive than alkynes but still more reactive than alkanes. 

Alkanes:

  • Alkanes only have single bonds, which are the least reactive of the three.
  • They are saturated and require more energy to break the bonds for a reaction to occur.
