The geometry of a molecule depends upon ...

The geometry of a molecule depends upon the repulsions between electron pairs present in the valance shell of the central atom. LP - LP repulsions are greater than LP-BP which are greater than BP - BP. A pi bond can not decide the geometry of a molecule because pi bond has no independent exsistance. Deviations in bond angle are due to the presence of lone pairs.
Which of the following molecule is linear in shape ?

A

`I_(3)^(-)`

B

`CO_(2)`

C

Both ` I_(3)^(-) ` and ` CO_(2)`

D

`SO_2`
