Is H2CS polar

Answer 1

Yes it is polar.

If you draw the Lewis Structure you have the central atom of Carbon single bonding to two hydrogen and double bonding to sulfur. There will be two lone pairs on Sulfur.

This will satisfy the octet rule, and create this molecule.

To see if it is polar, find if the dipole movements of the molecule cancel each other. In other words, look at the electronegativity and see if an element has more of a tendency to attract electrons. Since Carbon more electronegative than the Hydrogen, the electrons are more attracted to Carbon and therefore the dipole movements do not cancel out and therefore Sulfur has a slightly negative charge while Hydrogen and Carbon also have a slightly positive charge.

Also, since the molecule is asymmetrical, it is polar.

Hope that helps ! :)

Answer 2

Yes, H2CS (thioformaldehyde) is a polar molecule because it has a bent molecular geometry which creates an uneven distribution of charge. The sulfur atom has a higher electronegativity than the hydrogen and carbon atoms, leading to a separation of charges within the molecule.
