NEET Chemistry Nucleophilic Addition MCQ Question
If 0.1 moles of propanone reacts with an excess of hydrogen cyanide (HCN) in the presence of a base catalyst, what is the expected yield in moles of the cyanohydrin product assuming complete reaction?
0.1 moles
0.05 moles
0.2 moles
0.15 moles
Correct Answer
Detailed Explanation
According to the NCERT, aldehydes and ketones undergo nucleophilic addition with HCN to form cyanohydrins. Since 0.1 moles of propanone reacts with HCN, it will yield 0.1 moles of cyanohydrin product if the reaction goes to completion.
