Which of the following is correctly matched with the given property?
Options
- AM g S O 4 < C a S O 4 < S r S O 4 S o l u b i l i t y i n w a t e r < B a S O 4
- BB e C O 3 > M g C O 3 > T h e r m a l s t a b i l i t y C a C O 3 > S r C O 3 > B a C O 3
- CN a O C l > N a O B r > O x i d i s i n g n a t u r e N a O l
- DF 2 > C l 2 > B r 2 B o n d e n e r g y > l 2
Correct answer
C. N a O C l > N a O B r > O x i d i s i n g n a t u r e N a O l
Step-by-step solution
Solubility order: - M g S O 4 > C a S O 4 > S r S O 4 > B a S O 4 Thermal stability: - Ba C O 3 > S r C O 3 > C a C O 3 > M g C O 3 > B e C O 3 Correct order is N a O C l > N a O B r > N a O I = Oxidising nature E N of Helogen ↑ the tendency to gain of electron ↑ Oxidising nature ↑ Bond energy C l 2 > B r 2 > F 2 > I 2
