Aldehydes Ketones Question 233

Question: In the following sequence of reactions, what is D- $ A\xrightarrow{SOCl_2}B\xrightarrow{NaN_3}C\xrightarrow{heat}D $

Options:

A) Primary amine

B) An amide

C) Phenyl isocyanate

D) A higher hydrocarbon

Show Answer

Answer:

Correct Answer: C

Solution:

[c] $ C_6H_5CH_3\xrightarrow{[O]}\underset{[A]}{\mathop{C_6H_5COOH}}\xrightarrow{SOCl_2} $

$ \underset{[B]}{\mathop{C_6H_5COCl}}\xrightarrow{NaN_3}\underset{[C]}{\mathop{C_6H_5CON_3}} $

$ \xrightarrow{heat}\underset{UnstableBemzoylnitrene}{\mathop{[ C_6H_5-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-\overset{..}{\mathop{N}}: ]}}\xrightarrow{{}}\underset{Phenylisocyanate,[D]}{\mathop{C_6H_5NCO}} $
