What arrangement of electrons would result in a nonpolar molecule? – Q/A (Question and Answer)
Test Answer
Answer:
The bonding in the molecules have to be equally shared between the atoms
Explanation
A molecule is considered nonpolar if the electronegativity difference between the atoms is less than 0.5 and the bond dipoles cancel each other out. This can happen if the atoms are the same or if they have similar electronegativities.
CCl4Carbon has 4 valence electrons and chlorine has 7. So, in total there are 28 valence electrons in CCl4.
The electrons around the central atom should be arranged so that each atom has an octet (8 electrons).
.If the molecule has an odd number of electrons, add one electron to the central atom to give it a full octet. This will ensure that the molecule is electrically neutral and will help to minimize any potential repulsions between the electrons on the outermost shells of the atoms.
If the molecule has an even number of electrons, divide the electrons evenly between the atoms. This will result in each atom having an equal number of electrons and a net charge of zero.
A molecule is considered nonpolar if the electronegativity difference between the atoms is less than 0.4, and the bond dipoles cancel each other out. This means that the electrons are evenly divided between the atoms, and there is no net dipole.
Conclusion
A molecule is considered to be nonpolar if the electron pushing elements cancel each other out. This can happen if the molecule has a symmetrical shape, or if the molecule has an odd number of electrons.
