Question

Determine whether each molecule given below is polar or nonpolar.

a. PF3

b. CO2

c.CHCl3

d. H2O

Answer 1

In a polar molecule the atoms with more positive charge binds to the

one side and atoms with more negative charge binds to the another

side.

In a non polar molecule the electrons are distributed symmetrically

so there is no positive or negative charges obtained so

\(\mathrm{PF}_{3}\) is a polar molecule

\(\mathrm{CO}_{2}\) is a non polar molecule

\(\mathrm{CHCl}_{3}\) is a polar molecule \(\mathrm{H}_{2} \mathrm{O}\) is a polar molecule
