Physical Chemistry> Bond angle???...

question mark

Why is the bond angle of H2S shorter than H2O even though both oxygen and sulphur have two lone pairs each and have an angular shape and oxygen is more electronegative than sulphur???? and when the more electronegative atom is present then the bond angle will be less for that molecule right ...the how come the ans???Plzzz explainwill approve if right !!!

Well, the bond angle of H2S is shorter as it will not attract the electron cloud towards itself as strongly as oxygen due to the electronegativity difference. Hence, in water, the shared electrons remain shifted towrds oxygen due to which its bond angle is greater.
