[2008,
(a)
(b)
(c)
(d)
Show Answer
Solution:
- (d) Calculating the bond order of various species.
$\pi 2 p_x^{2} \pi 2 p_y^{2} \pi^{} 2 p_x^{2} \pi^{} 2 p_y^{1}$
Number of electrons in bonding B.O.
NO: $KK \sigma 2 s^{2} \sigma^{} 2 s^{2} \pi 2 p_x^{2} \approx \pi 2 p_y^{2} \sigma 2 p_z^{2} \pi^{} 2 p_x^{1}$
B.O.
B.O.
B. O.
From these values we find the correct order of increasing bond order is
