Answer to Question #327997 in General Chemistry for nina

Question

PCl3 and CH4 both have a tetrahedral electronic geometry but their molecular geometries are not  the same. What is the difference.

Answer 1

Form of PH3 is trigonal pyramidal. Molecular geometry around phosphorous atom is tetrahedral. Total valence electrons pairs around phosphorous atom is four.

The CH4 molecule has no dipole moment due to an equal charge distribution of negative and positive charges.The CH4 have tetrahedral electronic geometry.
