(ii) Al$_2$O$_3$	(b) Basic
(iii) N$_2$O	(c) Acidic
(iv) Cl$_2$O$_7$	(d) Amphoteric

Which of the following options has all correct pairs?

• A. (i)-(b), (ii)-(a), (iii)-(d), (iv)-(c)
• B. (i)-(c), (ii)-(b), (iii)-(a), (iv)-(d)
• C. (i)-(a), (ii)-(d), (iii)-(b), (iv)-(c)
• D. (i)-(b), (ii)-(d), (iii)-(a), (iv)-(c)

Answer 1

Answer: (D)

$Na_2O \to$ Basic
$Al_2O_3 \to$ Amphoteric
