The bond angle in h2s is 92.2 degree whereas the bond angle in h2o is 104.5 degree why
Answers
Answer:
This is due to the difference in electronegativity in H2O and H2S
Explanation:
In the water molecule oxygen atom is present which is more electronegative than sulfur in H2S ( electronegativity decreases down the group) .As the electronegativity of the central atom decreases the lone pair of electrons lie further from it and therefore lp- lp repulsion decrease. Hence bond angle decrease.
In water molecule where oxygen atom is more electronegative holds the lone pair of electrons on itself and therefore more lp-lp repulsion and more is the bond angle
Answer:
Bond angle is directly proportional to electronegativity of central atom.
Explanation:
The bond angle in H2S is 92.2 degree whereas the bond angle in H2O is 104.5 degree because of electronegativity of sulphur ( S ) is less than oxygen ( O ) so bond angle of H2S is less than H2O.
As sulphur is less electronegetive than oxygen thus there is less attraction of the electron pair towards itself that causes less repulsive force to act between the bonds and oxygen has high electronegativity so the repulsive force is more between the bonds. This results into more widening of the bond angle in H2O than H2S.
