સામાન્ય રીતે બંધક્રમાંક એ આણ્વિય ઘટકોની સ્થિરતાનો ખ્યાલ આપે છે. બધા જ અણુઓ જેવા કે \(H_2,\,\, Li_2\) અને \(B_2\) ના બંધક્રમાંક સમાન હોવા છતા તેઓ સમાન રીતે સ્થાયી નથી. તેઓની સ્થિરતાનો ક્રમ જણાવો.

A \({H_2} > {B_2} > L{i_2}\)
B \(L{i_2} > {H_2} > {B_2}\)
C \(L{i_2} > {B_2} > {H_2}\)
D એકપણ નહીં

Answer & Solution

Correct Answer

(D) એકપણ નહીં

Step-by-step Solution

Detailed explanation

None of the given option is correct. The molecular orbital configuration of the given molecules is \(H_2 = \sigma 1s^2\) (no electron anti-bonding) \(L{i_2} = \sigma 1{s^2}\,{\sigma ^*}1{s^2}\,\sigma 2{s^2}\,\) (two anti - bonding electrons)…

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
