Question

58. Statement I : The correct order of electronegativity of fluorine, oxygen nitrogen is F > O > N.

Statement II : The oxidation state of oxygen in OF₂ is +2 and in Na₂O is −2.

In the light of the above statements, choose the correct answer from the options given below

Options

A.Both Statement I and Statement II are true
B.Both Statement I and Statement II are false
C.Statement I is true but Statement II is false
D.Statement I is false but Statement II is true

Solution

Sol. Statement-I

(EN)F = 4.0

(EN)O = 3.5 on Pauling scale

(EN)N = 3.0

(EN)F > (EN)O > (EN)N

Statement-II

Oxidation state of oxygen in OF₂

OF₂ ⇒ x −1 × 2 = 0

x = +2

Oxidation state of oxygen in Na₂O

Na₂O ⇒ +1 × 2 + x = 0

x = −2

Both the statement I and statement II are correct.
