Organic Compounds Containing Halogens Question 106

Question: Identify $ X $ and $ Y $ in the following sequence $ C_2H_5Br\xrightarrow{X}product\xrightarrow{Y}C_3H_7NH_2 $

[Orissa JEE 2005]

Options:

A) $ X=KCN,Y=LiAlH_4 $

B) $ X=KCN,Y=H_3{O^{+}} $

C) $ X=CH_3Cl,Y=AlCl_3/HCl $

D) $ X=CH_3NH_2,Y=HNO_2 $

Show Answer

Answer:

Correct Answer: A

Solution:

$ C_2H_5Br\xrightarrow{KCN(X)}C_2H_5CN\xrightarrow{LiAlH_4(Y)} $

$ C_2H_5CH_2NH_2(C_3H_7NH_2) $

$ X=KCN,Y=LiAlH_4 $
