Question

Among O_{2}*N * C * H_{2} * C * H_{2} * O and C*H_{3} * C * H_{2} * O- which is more stable and why?​

Answer 1

Electronic configuration of H

2

+

is σ1s

1

σ

∗

1s

0

Bond order will be 1−0/2=1/2

Electronic configuration of H

2

−

is σ1s

2

σ

∗

1s

1

Bond order will be 2−1/2=1/2.

Bond order for both H

2

+

and H

2

−

is same but H

2

+

is more stable than H

2

−

due to absence of electrons in anti-bonding orbital.

Answer 2

Explanation:

Electronic configuration of H 2+ is σ1s 1 σ ∗ 1s 0

Bond order will be 1−0/2=1/2

Electronic configuration of H 2− is σ1s 2 σ∗ 1s 1

Bond order will be 2−1/2=1/2.

Bond order for both H 2+

and H 2− is same but H 2+ is more stable than H 2 − due to absence of electrons in anti-bonding orbital.
