Which of the following has linear geometry?

A)  \[l_{3}^{-}\]                           

B)  \[l_{2}^{+}\]

C)  \[{{H}_{2}}O\]                       

D)  \[S{{O}_{2}}\]

Correct Answer: A

Solution :

The structure of \[I_{3}^{\Theta }\] is determined as follows \[I_{3}^{\Theta }\] has 2 bond pairs and 3 lone pairs. According to VSEPR theory, geometry is linear and can be represented as follows \[Geometry = linear\] \[\operatorname{Hybridisation}=s{{p}^{3}}d\]
