Question

Among the following moleculas/ions `BeCl_(2) ,N_(3)^(-) ,N_(2)O,NO_(2)^(+),O_(3),SCl_(2),ICI_(2)^(-) ,I_(3)^(-) and XeF_(2)`,
the total number of linear molecule(s)ion(s) where the hybridization of the central atom does not have
contribution from the d-orbital(s) is
(Atomic number : S 16, Cl =37 ,I = 53 and Xe 54)

Answer 1

Correct Answer - 4
`BeCl_(2) to sp tp ` linear `SCl_(2) to sp^(3) to ` bent
`N_(3)^(-) to sp to ` linear `I_(3)^(-) to sp^(2)d to ` linear
`N_(2)O to sp to ` linear `Icl to sp^(3) d to ` linear
` NO_(2)^(+) to sp to ` linear `XeF_(2) to sp^(3) d to ` linear
`O_(3) to sp^(2) to ` bent
Thus , there are total four linear molecular/ions
where the hybridisation of the central atom does
not have contribution from the d-orbitals .
