Question

Match the following:

Oxide	Nature
(a) $CO$	(i) Basic
(b) $BaO$	(ii) Neutral
(c) $A{l}_2{O}_3$	(iii) Acidic
(d) $C{l}_2{O}_7$	(iv) Amphoteric

Which of the following is correct?

• A. $a-\left(iii\right);b-\left(iv\right);c-\left(i\right);d-\left(ii\right)$
• B. $a-\left(iv\right);b-\left(iii\right);c-\left(ii\right);d-\left(i\right)$
• C. $a-\left(i\right);b-\left(ii\right);c-\left(iii\right);d-\left(iv\right)$
• D. $a-\left(ii\right);b-\left(i\right);c-\left(iv\right);d-\left(iii\right)$

Answer 1

The correct option is D $a-\left(ii\right);b-\left(i\right);c-\left(iv\right);d-\left(iii\right)$

Generally metal oxides are basic in nature while nonmetal oxides are acidic in nature.

Neutral oxides are oxides which are neither acidic nor basic. $CO$ is neutral oxide.

Amphoteric oxides react with both acids and alkalis to form salt and water.​
$A{l}_2{O}_3$ is amphoteric oxide.
Option D is correct.
