Which of the following has a square pyramidal shape?
PCI5
BrF5
PF5
[Ni(CN)4]2-
The Correct Option is B
Solution and Explanation
\(BrF_5\) (Bromine pentafluoride) exhibits a square pyramidal molecular geometry. This is attributed to the presence of five electron domains surrounding the central bromine atom, one of which is a lone pair. Consequently, Bromine pentafluoride possesses 1 lone pair and 5 bonding pairs, leading to an octahedral electron geometry and a square pyramidal molecular shape.
\(BrF_5\) has 1 lone pair and 5 bond. Therefore, geometry is octahedral, shape is square pyramidal.
Accordingly, option (B) which states BrF5 is the correct choice.
