स्पीशीज़ \(Li _{2}, Li _{2}^{-}\) और \(Li _{2}^{+}\) की स्थिरता का बढ़ता क्रम है

  1. A \(Li_2 < Li_2^+ < Li_2^-\)
  2. B \(Li_2^- < Li_2^+ < Li_2\)
  3. C \(Li_2 < Li_2^- < Li_2^+\)
  4. D \(Li_2^- < Li_2 < Li_2^+\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(Li_2^- < Li_2^+ < Li_2\)

Step-by-step Solution

Detailed explanation

Correct option (b) \(\mathrm{Li}_{2}-<\mathrm{Li}_{2}^{+}<\mathrm{Li}_{2}\) Explanation: \(\mathrm{Li}_{2}(3+3=6)=\sigma 1 \mathrm{s}^{2}, \quad \hat{\sigma} 1 \mathrm{s}^{2}, \sigma 2 \mathrm{s}^{2}\) Bond order \(=\frac{N_{b}-N_{a}}{2}=\frac{4-2}{2}=1\)…
