4.Chemical Bonding and Molecular Structure
medium
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
B
$Li_2^ + $ is stable and $Li_2^ - $ is unstable
C
Both are stable
D
Both are unstable
(JEE MAIN-2019)
Solution
Both $Li_2^ + $ and $Li_2^ – $ have same bond order. But the number of antibonding electrons is less $Li_2^ + $ than in $Li_2^ – $
