Is H2S polar or nonpolar?

Answer:

H2S is a polar molecule.Again,hydrogen sulphide is polar molecule because of its bent shape(V type shape) which makes the net molecular dipole moment non zero.Again,Since H2S has net molecular dipole moment,H2S is polar.

Explanation:

Here are the few steps that you help you to determine that hydrogen sulphide,H2S, is a polar molecule.

           Step-1:

Draw the Lewis structure of H2S.

             Step-2:

After drawing Lewis structure of H2S,now you need to consider the electronegativity difference between atoms.

Here sulphur is more electronegative than hydrogen.So,every  sulphur-hydrogen bond is polar.

               Step-3:

Now consider bond dipole moment.

As both sulphur- hydrogen bonds are polar,every bond has a dipole moment.

             Step-4:

Now consider the geometry or shape of H2S molecule by applying VSEPR theory.

According to VSEPR theory,we get bent shape or geometry of H2S.

                 Step-5:

Now consider the net molecular dipole moment.

As the shape of H2S is bent(V type),one bond dipole moment does not  cancel another bond's dipole moment.Thus,we get non zero value for the net molecular dipole moment .As the value of net molecular dipole moment is not zero,we can say that H2S is polar.
