Classification of Elements and Periodicity in Properties - Result Question 8
####8. Match the oxide given in column A with its property given in column $B$ [NEET Odisha, 2019]
Column-A
(i) $Na_2 O$
(ii) $Al_2 O_3$
(iii) $N_2 O$
(iv) $Cl_2 O_7$
Which of the following options has all correct pairs?
(a) (i)-(B), (ii)-(D), (iii)-(A), (iv)-(C)
(b) (i)-(B), (ii)-(A), (iii)-(D), (iv)-(C)
(c) (i)-(C), (ii)-(B), (iii)-(A), (iv)-(D)
(d) (i)-(A), (ii)-(D), (iii)-(B), (iv)-(C)
Show Answer
Solution:
- (a) $Na_2 O$ basic oxide
$Al_2 O_3$ amphoteric oxide
$N_2 O$ neutral
$Cl_2 O_7$ acidic oxide
Elements of gp. 1 and 2 form besicoxides while gp. 13 and 14 elements form amphoteric oxides. Elements of gp. 16 and 17 form acidic oxides. Acidic character of oxides increases from left to right in the periodic table.
