Question

PLEASE EXPLAIN the REASON,Among the following oxides, the one which
is most basic is
(a) Zno
(b) Mgo
(c) A1,03
(d) N2O5​

Answer 1

Answer:

a)ZnO

Explanation:the basic nature of an oxidised element depends on its electropositivity. Since all metallic oxides are basic in nature . Here you should check which metal is most reactive. Electropositivity increases as you move downwards in a periodic table, since Zn lies in 4th period and other metals lie above it, Zn has more no.of shells and it can easily lose electrons even though it has more valence electrons than Mg.Hence ZnO is most basic in nature
