Which arrangement of electrons leads to anti-ferromagnetism?

View answer and explanation

Correct option: B

\uparrow \mathrm{ } \downarrow \mathrm{ } \uparrow \mathrm{ } \downarrow

Option B (

\uparrow \mathrm{ } \downarrow \mathrm{ } \uparrow \mathrm{ } \downarrow

) is correct because anti-ferromagnetism arises from the alignment of magnetic moments in opposite directions, resulting in a net magnetic moment of zero.
