Draw the Lewis structure and name the molecular
geometry for these molecules.
a. PF3
b. HCN (carbon is the central atom)
c. CF2Cl2 (carbon is the central atom)

Respuesta :

The Lewis structure of a molecule is a representation of the valence electrons in the molecule using dots.

The structure of a molecule is easily shown using dots to depict valence electrons and sometimes a dash to indicate two electrons that are shared in a bond.

The structures of PF3, HCN and CF2Cl2 have been shown here.

PF3 has a trigonal bipyramidal molecular geometry. HCN has a linear molecular geometry while CF2Cl2 has a tetrahedral molecular geometry. Note that the molecular geometry shows the number and arrangement of atoms present in the molecule.
