Which balanced chemical equation show the formation of ethyl chloride using thionyl chloride?
Correct answer: D. CH3COOH + SOCl2 -> CH3COCl + SO2 + HCI
- A. HCOOH + SOCl2 -> HCOCI + SO2 + HCI
- B. CH3CH2COOH + 2SOCl -> CH3CH2COCl + SO2 + HCI
- C. CH3CH2COOH + 2SOCl -> CH3CH2COC1 + SO3 + HCI
- D. CH3COOH + SOCl2 -> CH3COCl + SO2 + HCI
Explanation
Thionyl chloride is SOCl2 and it reacts with carboxylic acids to form acyl chlorides.Options B and C do not involve thionyl chloride, it mentions SOCl instead of SOCl2 so, they are incorrect.Options A and D are both valid reactions involving thionyl chloride. However, the question asks for the formation of ethanoyl chloride. Option A shows the formation of METHANOYL Chloride, whereby D shows ethanoyl chloride formation so, D is the correct answer.

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.
