Which of the following reagent is suitable for the preparation of the product in the above reaction?
Options
- ARed P + Cl 2
- BNaBH 4
- CNH 2 - NH 2 / C 2 H 5 O ⊝ N ⊕ a
- DNi / H 2
Correct answer
C. NH 2 - NH 2 / C 2 H 5 O ⊝ N ⊕ a
Step-by-step solution
In the given reaction, only the carbonyl group has been reduced while the carbon- carbon double bonds are unaltered. This is possible with the help of Wolf Kishner Reduction whose reagent set is given in Opiton (C). To reduce the carbonyl groups into alkane wolf - kischner reduction is used, without affecting the double bond.
