Hi,

 

I was going through some of the exam papers when I saw that H2S (hydrogen Sulphide) has a linear shape. I wondered that when 2 of the 6 electron on sulphur bind to 2 hydogen ones to make a bond, it leaves 4 electrons on sulphur which makes it 2 lone pair. The shape the mark scheme says is linear. I was wondering does the 2 lone-pairs of electron cancel each other effect in terms of repulsion because otherwise H2S should have had a trigonal shape.

 

help out. Thnx

it`s bond angle is not linear like CO2, it`s bent like H2O, the bond angle is 92 degrees.

it`s bond angle is not linear like CO2, it`s bent like H2O, the bond angle is 92 degrees

 

So wouldn't it make its shape trigonal?

nope, it`s just called Bent.

Tnx
