Question
Which one of the following orders presents the correct sequence of the increasing basic nature of the given oxides? (1) K2O
Options
A. Option 1
B. Option 2
C. Option 3
D. Option 4

Correct Answer

Option 2

Explanation

While moving from left to right in periodic table basic character of oxide of elements will decrease.

$? ?_{I n c r e a \sin g b a s i c s t r e n g t h}^{A l_{2} O_{3} < M g O < N a_{2} O}$

and while descending in the group basic character of corresponding oxides increases.

$? ?_{I n c r e a \sin g b a s i c s t r e n g t h}^{N a_{2} O < K_{2} O}$

$? C o r r e c t O r d e r i s A l_{2} O_{3} < M g O < N a_{2} O < K_{2} O$
