What is the molecular geometry of KrF2?
Molecular geometry takes into account the electrons as well when determining the geometry. The geometry of KrF2 is trigonal bipyramidal. The molecular shape does take into account the lone pairs on the central atom. Thus, the molecular shape of KrF2 is linear.
What is the bond angle of KrF2?
Can someone please help explain the logic why KrF2 has a linear shape and a bond angle of 180 degrees?
Is KrF2 polar or non polar?
Molecules with lone pairs around the central atom are generally nonsymmetric, meaning that the individual bond dipoles do not usually cancel each other out giving a polar molecule. Exceptions: KrF2 (linear shape) and XeF4 (square planar shape) type compounds are nonpolar even though the central atom has lone pairs.
