Which of the following is an alkyl halide:
Correct answer: D. All of these
- A. CH3CI
- B. C2H4CI2
- C. CH2CI2
- D. All of these
Explanation
Option D is correct. CH3Cl, C2H4Cl2, and CH2Cl2 are all alkyl halides. An alkyl halide is an organic compound that contains a carbon atom that is bonded to a halogen atom. The carbon atom is usually bonded to one or more hydrogen atoms as well. In CH3Cl, the carbon atom is bonded to three hydrogen atoms and one chlorine atom. In C2H4Cl2, the carbon atoms are bonded to two hydrogen atoms and two chlorine atoms. In CH2Cl2, the carbon atoms are bonded to two hydrogen atoms and two chlorine atoms.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
