Question

S₁:  E₂O₅ is less acidic than E₂O₃ (element E is belongs to 15^th group).

S₂ : E₂O₃ acidic strength decreases down the group (element E is belongs to 15th group). 

(1) Both S₁, & S₂ are true 

(2) Both S₁ & S₂ are false

(3) S₁. is true & S₂ is false

(4) S₁ is false & S₂ is true

Answer 1

Correct option is  (1) Both S1, & S2 are true

S₁: In 15th group oxide higher the oxidation state of element higher is acidic character
Example: P₂O₃ less acidic than P₂O_s.
15^th group
N₂O₃ Acidic
P₂O₃ Acidic
As₂O₃ Amphoteric
Sb₂O₃ Amphoteric
Bi₂O₃ Basic
