A) alcohol
B) water
C) kerosene
D) liquid ammonia
Correct Answer: C
Solution :
Alkali metals are highly reactive metals. They react with alcohol \[2{{C}_{2}}{{H}_{5}}OH+2K\xrightarrow{{}}2{{C}_{2}}{{H}_{5}}OK+{{H}_{2}}\] \[Water\xrightarrow[{}]{{}}2K+2{{H}_{2}}O\xrightarrow{{}}KOH+{{H}_{2}}\] \[K+(x+y)N{{H}_{3}}\xrightarrow{{}}\underset{\begin{smallmatrix} ammoniated \\ \,\,\,\,\,\,\,cation \end{smallmatrix}}{\mathop{[K{{(N{{H}_{3}})}_{x}}]}}\,+\underset{\begin{smallmatrix} ammonniated \\ \,\,\,\,\,\,\,elecron \end{smallmatrix}}{\mathop{{{[e{{(N{{H}_{3}})}_{y}}]}^{-}}}}\,\] But they do not react with kerosene.You need to login to perform this action.
