JEE Mains · Chemistry · STD 12 -8.1. Aldehydes and ketones
The increasing order of the following compounds towards \(HCN\) addition is
- A \((iii)\) \( < ( iv ) < ( ii ) < ( i )\)
- B \((iii)\) \( < ( iv ) < ( i ) < ( ii )\)
- C \((iii)\) \( < (1) < (i v) < (i i)\)
- D \((i)\) \( < (\) iii) \( < ( iv ) < ( ii )\)
Answer & Solution
Correct Answer
(C) \((iii)\) \( < (1) < (i v) < (i i)\)
Step-by-step Solution
Detailed explanation
Increasing order of reactivity towards \(HCN\) addition Greater the electrophilicity on \(\begin{array}{*{20}{c}} O \\ {||} \\ { - C - } \end{array}\) group greater the reactivity in nucleophilic addition. \((iii)\) \(< (1) < ( iv ) < ( ii )\)
