Select the incorrect order according to their given property -

Options

A. `C gt N gt O gt F`
[Order of Atomic radii]
B. `SO_(2) gt SO_(3)`
[Order of electronegativity of 'S' atom]
C. `He lt He^(+)`
[Order of Ionsiation energy]
D. `X (1s^(2) 2s^(1)) gt Y (Is^(2) 2s^(2) 2p^(1))`
[Order of electron affinity]

Answer

B

Explanation

`overset(+4)(SO_(2))" " overset(+6)(SO_(3))`
Thus S is `SO_(3)` is more electronegative
