    \[Cl\]\[\underset{neo-\,hexyl\,chloride}{\mathop{C{{H}_{3}}-\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-C{{H}_{2}}-C{{H}_{2}}Cl}}\,\] Select correct statement based on above scheme.

    A)  Layer X contains \[_{7}{{N}^{14}}{{+}_{0}}{{n}^{1}}{{\xrightarrow{{}}}_{6}}{{C}^{12}}{{+}_{1}}{{T}^{3}}\] and \[_{1}{{T}^{3}}\]

    B)  Layer Y contains \[\underset{4-bromo\,3-methyl\,butene-1}{\mathop{\overset{1}{\mathop{C{{H}_{2}}}}\,=\overset{2}{\mathop{C}}\,H-\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{\overset{3}{\mathop{C}}\,}}\,}}\,H-\overset{4}{\mathop{C}}\,{{H}_{2}}Br}}\,\] and \[CHC{{l}_{3}}+HN{{O}_{3}}\xrightarrow{{}}\underset{(tear\,gas)}{\mathop{\underset{chloropicrin}{\mathop{CC{{l}_{3}}N{{O}_{2}}}}\,}}\,+{{H}_{2}}O\] but amount of silver in this layer is smaller than in layer X

    C)  X and Yare immiscible layer

    D)  All are correct statements

    Correct Answer: D

    Solution :

    \[C{{H}_{3}}CHO\] and \[C{{H}_{3}}CO{{H}_{3}}\] in molten state are immiscible and form separate layers, zinc being lighter forms upper layer. Ag is soluble in both. Hence, all statements are correct.
