Chapter 10 problem 1

The correct choices are a) addition b)elimination c)substitution. a) Addition of the X and Y atoms/groups, without removing any atoms/groups, results in breaking of the π bond and formation of two σ bonds. This transformation is an addition reaction. b) Removal of the X atom/group and a hydrogen atom, without adding any atoms/groups, results in breaking of two σ bonds and formation of the π bond. This transformation is an elimination reaction. C) Removal of the X atom/group and addition of the Y atom/group results in no net change in the number of σ bonds in the molecule. This transformation is a substitution reaction.
