Question
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R:
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:
Select the correct option:
A
A is true but R is false
B
A is false but R is true
C
Both A and R are true and R is the correct explanation of A
D
Both A and R are true but R is NOT the correct explanation of A
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
For Assertion:Acetal and ketals are basically ethers hence they must be stable in basic medium but should break down in acidic medium.
Hence assertion is correct. For reason: Alkoxide ion (RO-) is not considered a good leaving group hence reason must be false.
