Question

Match the entries given in column $A$ with the appropriate ones in column $B$.

Answer 1

As $NaOH$ is a strong base, $N{a}_{2}O$ is most basic among the given oxides.

$N{a}_{2}O$ and $MgO$ - Basic

$A{l}_2{O}_3$ - Amphoteric(Basic and Acidic)

$Si{O}_2$ and $C{l}_2{O}_7$ - Acidic

$C{l}_2{O}_7$ id the most acidic and $Si{O}_2$ is weakly acidic.
