Predict the geometry of each interior atom in acetic acid.         O         = H3C-C-OH

A Lewis structure is a two-dimensional representation of a molecule that does not necessarily show what shape that molecule would take in three dimensions. From the given Lewis structure and what you know about VSEPR theory, identify the shape of the molecule. XV-X tetrahedral bent linear T-shaped trigonal planar octahedral trigonal pyramidal square planar see-saw square pyramidal trigonal bipyramidal

Determine whether each of the molecules below is polar or nonpolar. Linear F2   Tetrahedral SiF4   Linear CO   Trigonal planar BCl3

For which two molecules would you expect deviation from ideal bond angles? Ideal bond angles are angles you would expect from electron's geometry (i.e: Tetrahedral ideal bond angle is 109.5°) O H20 PCI5 SF6 O SO2
