Question
Electrons in bonds are negatively charged and therefore repel each other. If you had are a molecule of formula AB 3 , with A being the central atom, what would you predict the 3D shape to be to allow maximum distance between the three B atoms bonded to A ? A tripod-like or pyramidal -the shape, with A being the tip of the tripod and the B atoms being the " feet" of the tripod distanced less than 120° from each other A triangular shape, with A in the middle and all B atoms at 120° from each other AT shape, with A in the middle and the tip of the "".
Expert Solution
Step 1
In case of AB3,
*total number of electron pairs=3
case 1. if 3 bond pairs and zero lone pairs
then shape is trigonal planar and in this case angle will be 120 degrees or triangular shape with A in the centre and B atoms at 120 degrees.
for eg. BF3
B is the central metal atom and three B-F bonds are formed each 120 degrees.
