Question

Which one of the following orders presents the correct sequence of the increasing basic nature of the given oxides? (A) K 2 O < Na 2 O < Al 2 O 3< MgO (B) Al 2 O 3< MgO < Na 2 O < K 2 O (C) MgO < K 2 O < Al 2 O 3< Na 2 O (D) Na 2 O < K 2 O < MgO < Al 2 O 3

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

∴ Al_{2} O_{3} < MgO < N a_{2} O Increasing basic strength <br/> <br/>

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

∴ Na_{2} O < K_{2} O Increasing basic strength <br/> <br/>

∴

Correct order is

A l_{2} O_{3} < M g O < N a_{2} O < K_{2} O

Q. Which one of the following orders presents the correct sequence of the increasing basic nature of the given oxides?

$K_{2} O < N a_{2} O < A l_{2} O_{3} < M g O$

$A l_{2} O_{3} < M g O < N a_{2} O < K_{2} O$

$M g O < K_{2} O < A l_{2} O_{3} < N a_{2} O$

$N a_{2} O < K_{2} O < M g O < A l_{2} O_{3}$

Q. Which one of the following orders presents the correct sequence of the increasing basic nature of the given oxides?

K2​O<Na2​O<Al2​O3​<MgO

Al2​O3​<MgO<Na2​O<K2​O

MgO<K2​O<Al2​O3​<Na2​O

Na2​O<K2​O<MgO<Al2​O3​

$K_{2} O < N a_{2} O < A l_{2} O_{3} < M g O$

$A l_{2} O_{3} < M g O < N a_{2} O < K_{2} O$

$M g O < K_{2} O < A l_{2} O_{3} < N a_{2} O$

$N a_{2} O < K_{2} O < M g O < A l_{2} O_{3}$
