Find the predicted bond angle of hydrogen sulfide h2s using...

Transcript

00:01 Hello students welcome here in this question we have to predict the bond angles of h2a molecule by using valence bond theory okay so here the central atom is sulfur so the valence electrons in this one is valence electrons 3h2 and 3p4 is the valence electrons so how the electrons are arranged here so like this so here two electrons electrons here one one and two so they are two unpaid electrons in p -arbital so that's why the two electrons are of s1 so one s1 is a hydrogen electronic configuration so these two will get paired with this one electron so then covalent bond is formed between the hydro the sulfur and the two hydrogens so we can see that the sulfur having the bond bonds like this so this is 2d direction we are seeing actually these are arranged in 90 degrees angle okay so here we are seeing just this side this will be back side okay so 90 degrees angle will be between their p orbitals so here what happens the px p y and pz are arranged in like 90 degrees angles so then what happens the electrons are present here px two electrons are present this is px this is p y and p z so here it is one electron one electron is present here it is one electron is present so then what happens these hydrogens hydrogen will get combined this to this one so then what happens so here bond will be for formed with s orbital of hydrogen.

02:06 Okay, so h will come here.

02:09 So how can you write the bonds? so this is s.

02:14 Here, one loan paid of electron, one loan paid of electron.

02:19 So this one and this one.

02:21 You can write this one like this.

02:23 And here it is bonds.

02:26 And here we can write the s are hydrogens.

02:31 So hydrogen, here two electrons h...
