Polar bonds occur when the atoms that are bonded have an unequal sharing of electrons, they are not polar but just do not share electrons equally.

Polar molecules occur when the molecule has polar bonds that are not equally distributed ie water is polar molecule because its polar bonds act at 104.5 degrees from one another whereas a molecule that was straight, 180 degrees, would not be polar due to the equal distribution of the bonds. A tetrahedral molecule has bonds going equally in four directions, therefore, no polar bond but ammonia which is trigonal pyramidal has three bonds acting downwards at 104 degrees from one another, therefore, it is a polar molecule.

What is the bond angle for H2S?

The bond angle for H2S is approximately 92 degrees.


H2S molecular geometry?

The molecular geometry of H2S is bent, with a bond angle of approximately 92 degrees. This is because of the presence of two lone pairs on the sulfur atom, which push the hydrogen atoms closer together and give the molecule a bent shape.


Why bond angle of H2S is less than H2O?

The bond angle in H2S (92 degrees) is less than in H2O (104.5 degrees) due to the larger size of sulfur compared to oxygen. The larger size of sulfur results in weaker repulsions between the electron pairs, causing the bond angle to be smaller in H2S compared to H2O.


What is the size of hydrogen sulphide molecule?

According to wikipedia, one S-H side of the molecule spans a nominal 133.6 pm and the angle between the two arms of the molecule is 92.1o.


Is H2S a covalent bond?

NO!!! It is a compound of hydrogen and sulphur. The bonds between hydrogen and sulphur are covalent. H2S ( hydrogen sulphide) is the sulphur analogue of water. H2S is the bad eggs smell that is given off from rotten eggs.


Who has the most polar bond H2O H2S H2?

H2 molecule is the least polar. Between H2O and H2S, the most polar will be H2O as oxygen is more electronegative than sulphur.


What is Hydrogen sulfide shape is similar to?

Hydrogen sulfide (H2S) has a bent shape similar to water (H2O) due to its two lone pairs of electrons on the sulfur atom. This results in a bond angle of around 92 degrees in H2S, similar to the bond angle in water of approximately 104 degrees.


What is the shape of h2s molecule?

The hydrogen sulfide (H2S) molecule has a bent shape.


What molecule would be formed from atom of sulfur with atomic number 16 and atom formed from hydrogen with atomic number 1?

A molecule formed from a sulfur atom (S) with atomic number 16 and a hydrogen atom (H) with atomic number 1 would result in hydrogen sulfide (H2S). In this molecule, two hydrogen atoms bond with a sulfur atom to form a covalent bond.


Does H2S have a dipole moment?

Yes, hydrogen sulfide (H2S) does have a dipole moment because it is a polar molecule. The electronegativity difference between hydrogen and sulfur causes an uneven distribution of electron density, resulting in a dipole moment.


Why H2S is bent?

H2S is bent because it has a bent molecular geometry due to the lone pairs of electrons on the sulfur atom causing repulsion and pushing the hydrogen atoms closer together. This results in a bond angle of approximately 92 degrees.


Can h2s hydrogen bond?

H2S cannot form Hydrogen bonds.Electro negativity is not enough.
