 Classify the type of reaction given.

Possible Answers:

Rearrangement

Substitution

Elimination

Addition

Correct answer:

Elimination

An elimination reaction occurs when there is a release of atoms in a given compound to produce two or more products. In the reaction given a hydrogen and chloride atom are eliminated from the original compound to form hydrochloric acid and ethylene.

Example Question #12 : Help With Elimination Reactions

Screen shot 2016 02 21 at 7.20.17 am

 Classify the type of reaction given.

Possible Answers:

Heterolytic bond breaking

Addition

Homolytic bond breaking

Substitution

Correct answer:

Heterolytic bond breaking

Explanation:

Heterolytic bond breaking occurs in polar compounds to form to products of opposite charges. In these types of reaction two electrons from the original bond stays with one fragment upon cleavage. In the reaction given, the bond between the hydrogen and chlorine atom is broken with the two electrons from the original bond staying with the chlorine atom. The resulting products are hydrogen ion and chloride ion.
