Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason :
Assertion A : Acetal / Ketal is stable in basic medium.
Reason R : The high leaving tendency of alkoxide ion gives the stability to acetal/ ketal in basic medium.
In the light of the above statements, choose the correct answer from the options given below :
A is true but R is false
A is false but R is true
Both A and R are true but R is NOT the correct explanation of A
Both A and R are true and R is the correct explanation of A
Answers (1)
Acetal and ketals are basically ether hence they must be stable in basic medium but should break down in acidic medium.
Hence assertion is correct.
Alkoxide ion is not considered a good leaving group hence reason must be false.
