Rotate the molecule until you have a feeling for its three-dimensional shape. How many atoms are bonded to the central atom?
Consider the bond angle at the central atom. What is the approximate numerical value of this angle?
degrees.
You could view this geometry as being derived from a trigonal planar molecule by removing one atom, or as being derived from a tetrahedral molecule
by removing two atoms. Which does the bond angle suggest?
