Aldehydes Ketones Question 139
Question: The appropriate reagent for the transformation
[IIT-JEE (Screening) 2000]
Options:
A) $ Zn(Hg),HCl $
B) $ NH_2NH_2O{H^{-}} $
C) $ H_2/Ni $
D) $ NaBH_4 $
Show Answer
Answer:
Correct Answer: B
Solution:
Both $ Zn(Hg),HCl $ and $ NH_2NH_2,O{H^{-}} $ can reduce $ -COCH_3 $ group to $ -CH_2-CH_3 $ group, but HCl will also bring about dehydration of alcohol to form alkene. Therefore, appropriate reagent for the conversion is $ NH_2NH_2,O{H^{-}} $ .
