Question
Consider the following statements and determine which are true andwhich are false.KrF4 is a polar molecule.
Bond angles for IF6+ are 60 °.
NO3- has only two resonance Lewisstructures.
KrF4 has a tetrahedral structure.
The formal oxidation state of an atom in a molecule(or molecular ion) can be calculated as:
(the number of valence electrons on a free atom)minus (half the number of electrons in bonds to that atom)minus (the number of unshared electrons assigned to theatom in the molecule)
SeF4 is a polar molecule.
