trigonal pyramidal

Postby daisyjimenezt » Sat Nov 10, 2018 10:58 pm

can someone explain why trigonal pyramidal is the best shape to get the atoms the farthest away from each other?

Trigonal pyramidal is applicable when there's 3 atoms bonded to a central atom that has a lone pair. It is the ideal structure because the angles are <109 degrees.

In the trigonal pyramidal molecular shape there are three bonds and one lone pair on the central atom. This is the best shape because the lone pair on the central atom distorts the molecular shape to reduce lone pair-bonding pair repulsions. I'm sure this will be covered more in future lectures!

It is the best form because the bonding pairs and lone pairs are as far away as possible
