Why is the molecule nonpolar?
There are lone pairs on the central atom.
There are different types of elements bonded to the central atom.
There are no lone pairs on the central atom and all of the atoms bonded to the central atom are the same.
Why is the molecule polar?
The shape is bent and there are are lone pairs on the central atom.
There are different types of elements bonded to the central atom.
The molecule is symmetrical
Why is the molecule polar?
There is a lone pair on the central atom and a high electronegative nitrogen pulling the electrons.
There are different types of elements bonded to the central atom.
The electronegativities of the hydrogens pull the electrons away from the nitrogen.
Why is the molecule polar?
The molecule is symmetrical and the hydrogens cancel out the pulling of the Fluorine
There are different types of elements bonded to the central atom. The F pulls the electrons.
There are no lone pairs on the central atom and all of the atoms bonded to the central atom are the same.
Why is the molecule nonpolar?
There are lone pairs on the central atom.
There are different types of elements bonded to the central atom.
