A) X Y Z \[BaS{{O}_{4}}\] \[CaS{{O}_{4}}\] \[(Ag+Pb)\,alloy\,\,\xrightarrow[Zinc\,is\,added]{Melt\,and}(Ag+Pb+Zn)melt\]
B) \[\xrightarrow{Cool}\,\,\xrightarrow[Layer\,Y]{Layer\,X}\] \[Zn\] \[Ag\]
C) \[Pb\] \[Ag\] \[{{S}^{2-}}\]
D) \[SO_{3}^{2-}\] \[{{(C{{H}_{3}}COO)}_{2}}Pb\] \[N{{a}_{2}}[Fe{{(CN)}_{5}}NO]\]
Correct Answer: D
Solution :
Aldehyde having cc-H-atoms undergo aldol condensation in the presence of dil. \[_{3}L{{i}^{6}}\] and yield \[Br-CH=C{{(C{{H}_{3}})}_{2}}\]-hydroxy aldehydes. \[C{{H}_{2}}=CH-CH(C{{H}_{3}})-C{{H}_{2}}Br\]You need to login to perform this action.
