MCQ

According to molecular orbital theory, which of the following is true with respect to $Li_2^ + $ and $Li_2^ - $ ?

A
$Li_2^ + $ is unstable and $Li_2^ - $ is stable
✓
$Li_2^ + $ is stable and $Li_2^ - $ is unstable
C
Both are stable
D
Both are unstable

✓

Answer

Correct option: B.

$Li_2^ + $ is stable and $Li_2^ - $ is unstable

b
Both $Li_2^ + $ and $Li_2^ - $ have same bond order. But the number of antibonding electrons is less $Li_2^ + $ than in $Li_2^ - $
