The larger the central atom is the less the hydrogens have to spread out (because the electron repulsions are smaller) and the smaller the resulting angle.

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.

Give 2 examples in which the predicted bond angles are different from the actual bond angles?
In the case of ammonia (NH3), the predicted bond angle based on idealized geometry is 109.5 degrees, but the actual bond angle is around 107 degrees due to the presence of lone pairs repelling the bonded pairs. In the case of water (H2O), the predicted bond angle based on idealized geometry is 104.5 degrees, but the actual bond angle is around 104 degrees due to the presence of lone pairs repelling the bonded pairs.
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 molecular geometry of H20?
The molecular geometry of H2O is bent or angular. The oxygen atom is surrounded by two hydrogen atoms, resulting in a bent shape with a bond angle of approximately 104.5 degrees.
Is H2O ionic or covolant bond?
H2O (water) has a covalent bond between the hydrogen and oxygen atoms. In a covalent bond, the atoms share electrons to form a stable molecule.
Why is the H-O-H bond angle in water around 104 degrees?
The H-O-H bond angle in water is around 104 degrees due to the arrangement of electron pairs around the oxygen atom. The two lone pairs of electrons on the oxygen atom repel the bonded pairs, causing the molecule to adopt a bent shape and resulting in a bond angle of approximately 104 degrees.
According to VSEPR theory which molecule has a bent shape CO2 H2O CS2 HF?
H2O, with a bond angle of 104.5 degrees due to its three areas of electron density.
Does H2O or CaO have stronger bond?
H2O has a stronger bond then CaO because H2O is a covalent compound (made up of two nonmetals), whereas CaO is an ionic compound (made up of both a metal and nonmetal), and covalent bonds are stronger then ionic bonds.

Why is CaSO4 less soluble in water than NaCl?
CaSO4 is less soluble in water than NaCl because CaSO4 has a lower solubility product constant (Ksp) compared to NaCl. This means that CaSO4 molecules are less likely to dissociate into ions in water, resulting in lower solubility.
What is the bond agle of HOCl?
The bond angle of HOCl, which is the angle between the hydrogen-oxygen-chlorine atoms, is approximately 104.5 degrees. This is close to the ideal tetrahedral angle due to the lone pairs on the oxygen atom that distort the shape slightly.
Why bond angle in H2S is lower then H2O?
The lone pair - OH bond repulsion in water is greater than the OH bond- OH bond repulsion. In methane all of the bonds are the same so it has perfect tetrahedral symmetry. This is VSEPR theory
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.
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 an example of a covalent bond?
H2o
What Type Of Bond Does H2O Have?
H2O has a covalent bond. In a water molecule, the oxygen atom shares electrons with the two hydrogen atoms to form a stable bond.
What is the molecular geometry of H20?
The molecular geometry of H2O is bent or angular. The oxygen atom is surrounded by two hydrogen atoms, resulting in a bent shape with a bond angle of approximately 104.5 degrees.
Why is ozones bond angle larger than water H2O?
Water: 104.45° Ozone: 116.8° Difference: 12.4°
