Question

Quizplus · Accepted Answer

Secondary alkyl halides are defined as organic compounds containing a halogen atom attached to a carbon atom that is bonded to two other carbon atoms. In this case, structures I, II, and V fit this definition and are therefore secondary alkyl halides. Structure III is a primary alkyl halide because the carbon atom bonded to the halogen atom is only bonded to one other carbon atom. Structure IV is a tertiary alkyl halide because the carbon atom bonded to the halogen atom is bonded to three other carbon atoms. Therefore, the best choice is E, which includes all of the secondary alkyl halides in the given structures.
