Hydrocarbons Question 97
Question: $ \underset{CH}{\mathop{\overset{CH}{\mathop{|||}}}} $ reacts with acetic acid in presence of Hg2+ to give [BHU 2005]
Options:
A) $ \underset{CH{{(CH_3COO)}_2}}{\mathop{\overset{CH_3}{\mathop{|}}}} $
B) $ \underset{CH{{(CH_3COO)}_2}}{\mathop{\overset{CH{{(CH_3COO)}_2}}{\mathop{|}}}} $
C) $ \underset{CH_2(CH_3COO)}{\mathop{\overset{CH_3}{\mathop{|}}}} $
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
Reaction of acetic acid with acetylene is catalysed by Hg2+ salts.
$ HC\equiv CH\underset{Hg{{(OOCCH_3)}_2}}{\mathop{\xrightarrow{CH_3COOH}}}\underset{\text{vinyl acetate}}{\mathop{CH_2=CHOOCCH_3}} $
$ \underset{Hg{{(OOCCH_3)}_2}}{\mathop{\xrightarrow{CH_3COOH}}}\underset{\text{ethylidene diacetate}}{\mathop{CH_3-CH{{(OOCCH_3)}_2}}} $
