    At higher temperature, iodoform reaction is given by the dilute solution of:

    A)  \[NaB{{H}_{4}}\]   

    B)         \[{{B}_{2}}{{H}_{6}}\]

    C)         \[{{H}_{2}}{{O}_{2}}\]  

    D)        \[C{{H}_{3}}C{{O}_{2}}H/{{H}_{2}}S{{O}_{4}}\]

    Correct Answer: B

    Solution :

    lodoform test is used for the identification of functional  groups  like  \[N{{H}_{3}}\]and \[CO\] in     organic     compounds. \[N{{H}_{3}}\] upon hydrolyses at higher temperature yields. \[{{C}_{2}}O_{4}^{2-}\] and \[C{{u}_{2}}{{(SCN)}_{2}}\]lodoform test is given by \[C{{u}_{2}}O\] This dil. solution \[C{{u}_{2}}{{I}_{2}}\] gives positive iodoform test. \[C{{u}_{2}}C{{O}_{3}}\] \[C{{u}_{2}}O\]                                  \[FeS\]
