Question

A molecule must be nonpolar if the molecule1. is liner2. is neutral3. has ionic and convalent bonding4. has a symmetrical charge distribution

Answer 1

has a symmetrical charge distribution

Step-by-step explanation:

A symmetrical charge distribution means the atoms have the same electronegativity or they are a molecule with the same atoms in a regular pattern around the center is in CH4, identical along a central line.

Answer 2

4. has a symmetrical charge distribution

Step-by-step explanation:

Symmetrical charge distribution in molecules results in the formation non-polar molecules.

For a symmetrical distribution of charge to occur, there must be a sort of sharing of electrons between two atoms. In the case where electrons are transferred, there won't be any need to distribute charges.

When electrons are shared between atoms with similar likeness for the electron, none of the two atoms pulls the electrons more to itself. The electrons are shared evenly and symmetrically between the two atoms. This leaves no charge separation on any of the atom. Therefore, the dipoles in one direction cancels out the dipoles in another direction and this leaves no charge.

This makes the molecule non-polar.
