$Which of the following oxides is most acidic?$

Topic: NEET PYQ

Answer: C. Full step-by-step solution below.

A $A s_{2} O_{5}$
B $P_{2} O_{5}$
C $N_{2} O_{5}$
D $S b_{2} O_{5}$

Correct answer: C

Solution

(c) As among N, P, As and Sb, the former has highest electronegativity (EN) so its oxide is most acidic. As the electronegativity value of element increases, the acidic character of the oxide also increases.
