Hydrocarbons Question 110
Question: $ \underset{CH}{\mathop{\overset{CH}{\mathop{|||}}}}\xrightarrow{O_3/NaOH}X\xrightarrow{Zn/CH_3COOH}Y $ -Y- is [AIIMS 1988]
Options:
A) $ \underset{CH_2OH}{\mathop{\overset{CH_2OH}{\mathop{|}}}} $
B) $ CH_3CH_2OH $
C) $ CH_3COOH $
D) $ CH_3OH $
Show Answer
Answer:
Correct Answer: A
Solution:
$ (CH\equiv CH)\underset{NaOH}{\mathop{\xrightarrow{O_3}}}\underset{\overset{|}{\mathop{O}}-\overset{|}{\mathop{O}}}{\overset{\begin{smallmatrix} O \\ \hat{\ } \end{smallmatrix}}{\mathop{CH-CH}}}\xrightarrow{Hydrolysis} $
$ \underset{Glyoxal}{\mathop{CHO-CHO}}\underset{CH_3COOH}{\mathop{\xrightarrow{Zn}}}\begin{matrix} \underset{|}{\mathop{CH_2}}-OH \\ CH_2-OH \\ \end{matrix} $
