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

∙ 11y agoThe HOH bond angle in water is 104.50, the HSH bond angle in hydrogen sulfide is less at 92.10. The O-H bond length is 95.84 pm and the S-H bond length is longer at 133.6 pm.
Two explanations, the most intuitive is the VSEPR:-
VSEPR theory- this predicts that the lone pair-bonding pair repulsion is greater than bonding pair-bonding pair. This explains why the HOH angle is decreased from the ideal tetrahedral shape. In H2S the reduced electronegativivty of the S atom leads to the lone pair bing further away from the atom and causing an even greater repulsion.
Hybridisation- as you go down group 16 the tendency is for s electrons to take less part in the bonding and the angles get closer to 900 as the p "character" increases.

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 the equation for photosynthesis using CO2 and H2S?
It is not using H2S gas. It is using H2O liquid.
Why the conc h2so4 cant be used in preparation oh h2s?
h2so4 being good oxidising agent oxidises the h2s to h2o and free sulphur.so conc h2so4 cant be used in preparation of h2s gas
What are the main gases released in a volcano?
H2o,co2,so2,h2,co,h2s,hcl,hf
Are inorganic compounds bonded to hydrogen?
Yes. NH3, H2O, H2S, H2SO4; anything without carbon is an inorganic compound.
What is the bond angle for H2S?
The bond angle for H2S is 92.1­°.
Why bond angle of H2S is less than H2O?
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.
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.
Why H2O is liquid and H2S is gas?
intermolecular hydrogen bonding that is prsnt in H2O while absnt in H2S....:)
Why is the boiling point of AsH3 lower thanNH3?
NH3 is more polar than AsH3, this is the same as comparing H2O and H2S.
Strongest acid HCl H2O HI H2S ranking weakest to strongest?
Strongest---------------> Weakest HI, HCl, H2S, H2O According to MasteringChemistry.com
What is the equation for photosynthesis using CO2 and H2S?
It is not using H2S gas. It is using H2O liquid.
Balance this equation lioh plus h2s equals li2so4 plus H2O?
liho+h2s=
Why are the structures of H2S and H2O so similar?
h2so4
What is the reaction equation for CH3CSNH2 and H2O?
Ch3conh2 + h2s
Why the structure of H2S and H2O so similar?
h2so4
What is Hydrogen sulfide shape is similar to?
Water. The shape of the H2S atom is not quite identical to the shape of H2O, because the angle the atoms make is a few degrees off.
