Vedclass · Answer

(C) The acidic character of non-metallic oxides increases with an increase in the oxidation state of the central atom and decreases down the group as metallic character increases.Comparing the oxidation states: $P$ in $P_4O_6$ is $+3$,$P$ in $P_4O_{10}$ is $+5$,$As$ in $As_4O_6$ is $+3$,and $As$ in $As_4O_{10}$ is $+5$.Since $As$ is more metallic than $P$,its oxides are less acidic than the corresponding oxides of $P$.Between $As_4O_6$ and $As_4O_{10}$,$As_4O_6$ has a lower oxidation state $(+3 < +5)$,making it the least acidic among the given options.
