We’re being asked to determine which among the given compounds is a radical.
Recall that radicals are an exception to the octet rule which occurs when there is an odd number of electrons in an atom.
For this problem, we need to draw the Lewis structure for each compound.
To do so, we need the following steps:
Step 1: Determine the central atom in this molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
Consider the following XF4 ions: PF4–, BrF4–, ClF4+, and AlF4–. Which of the ions have more than an octet of electrons around the central atom?
