Question:

Statement I: Glycosides are hydrolyzed in acidic conditions

Statement II: Glycosides are acetals

Options:

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I

Both Statement I and Statement II are correct and Statement II is not the correct explanation of Statement I

Statement I is correct but Statement II is false

Statement I is false but Statement II is correct

Correct Answer:

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I

Explanation:

The correct answer is (1) Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I.

Statement I:  Glycosides are hydrolyzed in acidic conditions. This is because the glycosidic bond is a type of acetal bond, which is unstable in acidic conditions. The acidic conditions cause the acetal bond to break, releasing the two sugar molecules that make up the glycoside.

Statement II:  Glycosides are acetals. Acetals are a type of ether bond that is formed between an alcohol and an aldehyde or ketone. The glycosidic bond is a type of acetal bond, which is formed between the hydroxyl group of one sugar molecule and the aldehyde group of another sugar molecule.

Therefore, both statements are correct and Statement II is the correct explanation of Statement I.
