A) \[{{1}^{o}}\] and \[{{2}^{o}}\] amines
B) \[{{2}^{o}}\] and \[{{3}^{o}}\] amines
C) (a) & (b)
D) none of these
Correct Answer: C
Solution :
Hinsbergs reagent (benzene sulphonyl chloride) is used to distinguish between \[{{1}^{o}},\]\[{{2}^{o}}\] and \[{{3}^{o}}\] amines. \[{{1}^{o}}\,\text{amines+H}\text{.R}\text{.}\xrightarrow[{{H}_{2}}O]{NaOH}colourless\] \[solution\xrightarrow{acidified}\text{insoluble}\] \[{{2}^{o}}\,\text{amines+H}\text{.R}\text{.}\xrightarrow[{{H}_{2}}O]{NaOH}\text{insoluble}\] \[\xrightarrow{acidified}\text{insoluble}\] \[{{3}^{o}}\text{amines+H}\text{.R}\text{.}\xrightarrow[{{H}_{2}}O]{NaOH}\text{insoluble}\] \[\xrightarrow{acidified}colourless\,solution\]You need to login to perform this action.
