Among the following, the one which is most basic is
A.
$$ZnO$$
B.
$$MgO$$
C.
$$A{l_2}{O_3}$$
D.
$${N_2}{O_5}$$
Answer :
$$MgO$$
Solution :
$$ZnO$$ and $$A{l_2}{O_3}$$ are amphoteric oxide, $${N_2}{O_5}$$ is oxide of non-metal, so it is acidic and hence, $$MgO$$ is most basic among $$A{l_2}{O_3},ZnO,{N_2}{O_5}$$ and $$MgO.$$
