Potassium is kept in

Options

A. Alcohol
B. Water
C. Kerosene
D. Liquid ammonia

Answer

C

Explanation

Alkali metals are highly reactive metal. They react with
`{:("Alcohol",,-2C_(2)H_(5)OH+2K rarr 2C_(2)H_(5)OK+H_(2)),("Water",,-2K+2H_(2)O rarr 2KOH+H_(2)),("Ammonia",,underset("Ammoniated cation")(-K+(x+y)NH_(3)) rarr underset("Ammoniated electron")([K(NH_(3))_(x)]^(+)+[e(NH_(3))_(y)]^(-))):}`
But they do not react with kerosene.
