    An organic compound with molecular formula \[{{C}_{3}}{{H}_{5}}N\]on hydrolysis forms an acid which reduces Fehling's solution. The compound can be

    A)  ethanenitrile                    

    B)  ethyl carbylamines

    C)  ethaoxyethane               

    D)  propane nitrile

    Correct Answer: B

    Solution :

                     Carbylamines on hydrolysis give formic acid which reduces Fehling's solution. \[\underset{ethyl\text{ }carbylamine}{\mathop{{{C}_{2}}{{H}_{2}}NC}}\,+2{{H}_{2}}O\xrightarrow[{}]{{{H}^{+}}}\underset{ethylamine}{\mathop{{{C}_{2}}{{H}_{5}}N{{H}_{2}}}}\,\] \[+\underset{formic\text{ }acid}{\mathop{HCOOH}}\,\]
