Trigonal Pyramidal and it's consequences

Postby Michelle Fu 1H » Sat Nov 17, 2018 6:20 pm

So other than Trigonal Pyramidal shape, all other shapes have equivalent angles between regions of electron density. What consequences (physical, chemical etc) does the fact that trigonal pyramidal shape has all different angles have, if any?

The electron density around lone pairs are stronger than bonded pairs. Thus, the other pairs are repelled slightly from the lone pair, pushing them closer together and resulting in angles slightly less than the normal 109.5º that a tetrahedral has.
