CBSE Class 10 Science Practical Skills – Reactivity Series

2018/8/26· Metals can be arranged on the basis of relative reactivity. The arrangement of metals in a vertical column in order of their decreasing reactivity downwards is called the reactivity series of metals. In reactivity series, the most reactive metal (K) is placed at the top of the series while the least reactive metal (Au) is placed at the bottom.

Amine Reactivity - Chemistry

One important method of preparing 1º-amines, especially aryl amines, uses a reverse strategy. Here a strongly electrophilic nitrogen species (NO 2(+)) bonds to a nucleophilic carbon compound. This nitration reaction gives a nitro group that can be reduced to a 1º-amine by any of several reduction procedures.
