The number of species from the following which have square pyramidal structure is _______PF5,BrF−4,IF5,BrF5,XeOF4,ICl−4
Question
The number of species from the following which have square pyramidal structure is
PF5, BrF−4, IF5, BrF5, XeOF4, ICl−4
Solution
The molecular geometry of a molecule can be determined using VSEPR theory which predicts the 3D shape of individual molecules based upon the extent of electron-pair electrostatic repulsion.
-
PF5: Phosphorus pentafluoride has a trigonal bipyramidal geometry.
-
BrF−4: Bromine tetrafluoride ion has a square planar geometry.
-
IF5: Iodine pentafluoride has a square pyramidal geometry.
-
BrF5: Bromine pentafluoride has a square pyramidal geometry.
-
XeOF4: Xenon oxytetrafluoride has a square pyramidal geometry.
-
ICl−4: Iodine tetrachloride ion has a square planar geometry.
So, the number of species from the given which have square pyramidal structure is 3 (IF5, BrF5, XeOF4).
