Question

Among the following how many of the molecules are linear.

${\text{CO}}_2,{\text{NO}}_2^{-},{\text{SO}}_2,{\text{N}}_3^{-},{\text{C}}_2{\text{H}}_2,{\text{I}}_3^{-},{\text{XeF}}_2,{\text{CS}}_2$

Answer 1

Answer: 6

${\text{CO}}_{\text{2}}\text{,}{\text{N}}_{\text{3}}^{-}\text{,}{\text{C}}_{\text{2}}{\text{H}}_{\text{2}}\text{,}{\text{I}}_{\text{3}}^{-}\text{,}{\text{XeF}}_{\text{2}}\text{,}{\text{CS}}_{\text{2}}$
these are all linear in structure
