The bond lengths of C_2 , N_2 and B_2 molecules are X_1 ,X_2 and X_3 pm respectively. The correct order of their bond lengths is

Question

Accepted Answer

Correct answer: A. (a) M .O . :B_2 (10 )= KK^* 2 s^2 ( 2 s^* )^2( ^12p_x= ^12p_y) ;B .O .= 12 (4-2 )=1C_2 (12 )= KK^* 2 s^2 ( 2 s^* )^2( ^22p_x= ^22p_y) ;B .O .= 12 (6-2 )=2 N_2 (14 )= KK* 2 s^2 ( 2 s^* )^2( ^22p_x= ^22p_y) ^22p_z ;B .O .= 12 (5-2 )=3 Greater the bond order shorter is the bond length. ∴ X_3>X_1>x_2 .

$The bond lengths of C_{2}, N_{2} and B_{2} molecules are X_{1}, X_{2} and X_{3} pm respectively. The correct order of their bond lengths is$
