Decresing Order of bond dissociation energy wrt C- X bond

Answer will be cbad in decreasing order.More the Alpha hydrogen more Will be stability.

Examples which bond you have to break as asked by question.Most stable bond will need more energy to break it so you can link it with stability of the double bondSearch criteria of Alpha hydrogen will apply here also the more the Alpha hydrogen surrounding the double bond more stability and more will.Be energy needed to break it
