Nitrogen Containing Compounds Question 149
Question: $ C_6H_5NH_2\xrightarrow{NaNO_2HCl}X\xrightarrow{Cu_2{{(CN)}_2}}Y\xrightarrow{H_2O/{{H}^{+}}}Z $ Z is identified as : [Pb. PMT 2004]
Options:
A) $ C_6H_5-NH-CH_3 $
B) $ C_6H_5-COOH $
C) $ C_6H_5-CH_2-NH_2 $
D) $ C_6H_5-CH_2-COOH $
Show Answer
Answer:
Correct Answer: B
Solution:
$ C_6H_5NH_2\xrightarrow{NaNO_2/HCl}\underset{(X)}{\mathop{C_6H_5N_2Cl}}, $ $ \xrightarrow{Cu_2{{(CN)}_2}}\underset{(Y)}{\mathop{C_6H_5}},CN\xrightarrow{H_2O/{{H}^{+}}}\underset{\text{Benzoic acid (}Z\text{)}}{\mathop{C_6H_5-COOH}}, $ Thus product Z is identified as $ C_6H_5-COOH $
