In general formula of alkyl halide RX, X represents _
Correct answer: B. Halogens
- A. Noble gases
- B. Halogens
- C. Metals
- D. Metalloids
Explanation
Alkyl halides (RX, where R is an alkyl group and X is F, Cl, Br, or I) are classified as primary, secondary, or tertiary according to the degree of substitution at the carbon to which the halogen is attached.

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.
