Question

If all of the electron groups around a single central atom are bonding, and the same outer atom is bonded to the central atom in each case, is the molecule polar, nonpolar, or does it depend on the identity of the outer atom?

Answer 1

Answer:

It depends on the identity of the outer atom

Explanation:

We must recall that the polarity of a molecule depends on difference In electronegativity between atoms as well as the shape of the molecule.

When a central atom has no lone pairs and all the groups in the molecule are bonding, the identity and arrangement  of the outer atoms will determine the polarity of the molecule.

A polar molecule is formed by certain types of outer atoms arranged in  certain ways around the periodic table and vice versa.
