Given below are two statements : Statement I: The number of pairs...

Statement I:
$Al_2O_3$ and $Cr_2O_3$ are both amphoteric oxides.
$Cl_2O_7$ and $Mn_2O_7$ are both acidic oxides.
$Na_2O$ and $V_2O_3$ are both basic oxides.
$CO$ and $N_2O$ are both neutral oxides.
All $4$ pairs contain oxides of the same nature. Hence, Statement I is true.

Statement II:
$Na_2O$ is a strongly basic oxide.
$Al_2O_3$ is an amphoteric oxide.
$CO$ is a neutral oxide.
$Cl_2O_7$ is a strongly acidic oxide.
Thus, the most basic oxide is $Na_2O$ and the most acidic oxide is $Cl_2O_7$. Hence, Statement II is true.

Both Statement I and Statement II are true.

Answer: Both Statement I and Statement II are true
