    The silver salt of an unknown monoacidic alkyne contains 67.08% silver. The structure of the alkyne is

    A) \[s=\frac{{{t}^{2}}}{4}\]

    B) \[T\propto V\]

    C) \[T\propto {{V}^{2}}\]         

    D) \[T\propto \frac{1}{{{V}^{2}}}\]

    Correct Answer: A

    Solution :

                    Monoacidic alkyne is that having one hydrogen attached to the triple bonded carbon. In            \[\omega \] molecular weight of Ag salt of above compound will be 161 \[R/2\]  161 g of compound contains\[\frac{4\omega }{5}\] \[\frac{2\omega }{5}\]   100 g of compound contains \[\frac{3\omega }{5}\] So, the correct answer is \[\frac{2\omega }{3}\]
