D

Liquid ammonia

Text Solution

Verified by Experts

The correct Answer is:
C
Alkali metals are highly reactive metals. They react with Alcohol -`2C_(2)H_(5)OH +2K to 2C_(2)H_(5)OK+H_(2)`
Water -`2K +2H_2O to 2KOH + H_(2)`
Ammonia `-K + (x+y) NH_(3) to underset("Ammoniated cation")([K(NH_(3)_(x)])+underset("Ammonia electron")([e(NH_(3))_(y)]^(-))`
But they do not react with kerosene.
