Angle for bond

Postby Jamie Lee 1H » Sun Nov 17, 2019 3:27 pm

I missed the part in lecture about the bond angle value for a tetrahedral arrangement molecule but it has a bent geometry. I know we don't have to know the exact value but what was the range mentioned?

I believe that you simply need to give an indication that it will be less than 109.5 and in case of other repulsions acting on it, you could mention that it could be lesser. For example, if its is already less than 109.5, then the lone-bonding pair interaction could also be acting on it reducing the angle more.

The bond angle would be less than 109.5 because the lone pair repulsion is greater than bonding pair repulsion.

The range mentioned in class was less than 109.5, due to the lone pairs forcing bonding e- closer together.
