Question

based on the vsepr theory, what molecular shape can be predicted if a molecule has two paired electrons and one unshared pair of electrons around the central atom?
trigonal planar structure
tetrahedral structure
bent structure
linear structure

Explanation:

According to VSEPR theory, when there are three electron - pair groups (two bonded pairs and one lone pair) around the central atom, the electron - pair geometry is trigonal planar. But because of the repulsion from the lone pair, the molecular shape is bent. Trigonal planar structure has three bonded pairs and no lone pairs. Tetrahedral structure has four electron - pair groups (bonded or lone). Linear structure has two electron - pair groups (usually two bonded pairs with no lone pairs or two double bonds in some cases).

Answer:

bent structure
