Cl-Be-Cl N≡N: →O sp, linear sp, linear N- =N+ =N- O =N+ = O sp, linear sp, linear like I3-, XeF2 → sp3d, Linear Ans. = 4

Cl−Be−ClN≡N:→O sp, linear sp, linear N−=N+=N−O=N+=O sp, linear sp, linear like I3−​,XeF2​→sp3d, Linear Ans. =4

$Cl - B e - Cl N \equiv N : \to O$
sp, linear sp, linear
$N^{-} = N^{+} = N^{-} O = N^{+} = O$
sp, linear sp, linear
like $I_{3}^{-}, X e F_{2} \to s p^{3} d$ , Linear
Ans. $= 4$
