Bond angle is 109.5 degrees. Linear- In linear molecular geometry, the center atom has two molecules connected to it. Bond angle is 180 degrees. Trigonal-bipyramidal- In this type of molecular ...

As balloons are popped the resulting number conforms to the molecular shapes of VSEPR theory ... Show how the five now conform to trigonal bipyramidal shape. Continue popping balloons one at a time, ...
