Assertion (A): Alkyl flouride can be prepared by treating alkyl chloride with
Reason (R): Swart's Reaction is not used to prepare alkyl flouride.
Reason (R): Swart's Reaction is not used to prepare alkyl flouride.
View answer and explanation
Correct option: C
Assertion (A) is true, but Reason (R) is false
Option C is correct because Alkyl fluorides can be prepared by treating alkyl chlorides with AgF (Swarts reaction), making the assertion true, but the reason is false because Swarts reaction *is* used to prepare alkyl fluorides.
