Question

molecular geometry

A model for NO is shown in the chem3D window. NO2 has bent geometry. This geometry is sometimes called angular or V-shaped geometry. ball & stick |-+ labels 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? 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? degrees. For practice, type in the name of the geometry of the molecule

Explanation / Answer
