Question

15 multiple choice 2 points what is an addition reaction in organic chemistry? a reaction that involves the exchange of atoms between reacting molecules. a reaction where elements are removed from a molecule, typically involving the conversion of sigma bonds to pi bonds. a reaction where elements are added to a molecule, typically involving the conversion of a pi bond to two sigma bonds. a reaction where molecules are broken down into smaller units without the formation of new bonds. previous

Explanation:

• Option A describes a metathesis reaction (exchange of atoms).
• Option B describes an elimination reaction (removal of elements).
• Option C correctly defines an addition reaction (addition of elements, pi - bond to sigma - bonds conversion).
• Option D is not a standard organic reaction type as described (no new bond formation in a way that fits a common reaction category).

Answer:

C. A reaction where elements are added to a molecule, typically involving the conversion of a pi bond to two sigma bonds.
