Sort these molecules according to their polarity. a. HBr
b. CO2
c. BF3
d. H2
e. CH4
f. NH3

Polar molecules- NH3, HBr

Nonpolar molecules- CO2, BF3, H2, CH4

Explanation:

NH3 is polar because the three N-H bonds are in non symmetrical trigonal pyramidal arrangement, hence there is a resultant dipole moment that makes the molecule polar. The electro negativity difference between hydrogen and bromine makes HBr a polar molecule.

CO2 and BF3 are non polar because the individual dipoles in the molecule cancels out. CH4 is composed of two atoms of almost similar electro negativities hence it is non polar. H2 is contains a homonuclear covalent bond hence the molecule is nonpolar.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
