Type: MCQ-numerical-Hard-Class 12

If 0.5 moles of acetone undergo nucleophilic addition with excess hydrogen cyanide (HCN) in the presence of a base catalyst, how many moles of cyanohydrin are formed assuming the reaction goes to completion?

A

0.5 moles

B

0 moles

C

0.25 moles

D

0 moles

Correct Answer
