SN1 reactions are favoured by which of the following solvents?
Correct answer: A. Water
- A. Water
- B. Benzene
- C. Carbon tetrachloride
- D. Carbon disulphide
Explanation
Water is a polar protic solvent. In SN1 reactions, the nucleophile is not involved in the rate-determining step, and a polar protic solvent helps stabilize the carbocation intermediate. Water, being a polar solvent with the ability to solvate ions and stabilize charges, is suitable for SN1 reactions. Therefore, option a is correct.

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.
