Given below are two statements:
Statement I: The nucleophilic addition of sodium hydrogen sulphite to an aldehyde or a ketone involves proton transfer to form a stable ion.
Statement II: The nucleophilic addition of hydrogen cyanide to an aldehyde or a ketone yields amine as final product.
In the light of the above statements, choose the most appropriate answer from the options given below:
- Both Statement I and Statement II are true.
- Statement I is true but Statement II is false.
- Statement I is false but Statement II is true.
- Both Statement I and Statement II are false.
Correct answer: Statement I is true but Statement II is false.
Solution
Statement I is correct because the addition of sodium hydrogen sulfite to aldehydes or ketones does involve a proton transfer that leads to the formation of a stable bisulfite adduct. However, Statement II is incorrect because the reaction of hydrogen cyanide with aldehydes or ketones typically forms a cyanohydrin, not an amine.
