Concept explainers
Interpretation:
The best possible Lewis structure for free radical
Concept Introduction:
Free radicals are the molecules that contain the unpaired electrons.
A Lewis structure is used to represent the valence electrons of an atom and the bonds present in a molecule.
Dots in the Lewis structure represent the valence electrons.
Total number of electrons for Lewis structure can be calculated by summing the valence electrons of each atom in the molecule.
Once a Lewis structure is drawn, it is possible to identify the shape of the molecule using the VSEPR theory.
VSEPR stand for valence shell electron pair repulsion theory. It uses chemical formula, number of bonds and lone pairs to predict the shape of molecules.
A lone pair of electron means that it is has two electrons.
