Bond angle of SO2 H2S SO3

Explanation:

In SO2 , the bond angle is 119^∘ whereas in SO3 , the bond angle is 120^∘ .H2S = 92.1°

In SO2 , the bond angle is 119^∘ whereas in SO3 , the bond angle is 120^∘ .

Explanation:

S atom in both SO2 and SO3 is sp^2-hybridized.

There are 3 bonding sets of electrons and one non-bonding pair on the sulphur. So the shape is based on a tetrahedral structure - but the extra repulsion of the non-bonding pair will decrease the O-S-O angles by a few degrees from the 'perfect' tetrahedral angle.

The bonding in SO3 can be described as a combination of 3 resonance forms of 1 double and 2 single bonds. The SO2 molecule has a dipole moment, The starting point of 109.5 degrees is only applicable for 4 electron regions round the central atom. In SO2, we have 2 double bonds and one lone pair ; 3 electron regions so the default angle is 120 degrees. The extra repulsion of the lp vs double bonds accounts for reduction to 119. S atom in both SO2 and SO3 is sp2-hybridized. But it is related to dipole moment and assertion is the explanation from bent angle so here reason is unable to give explanation of assertion.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
