(a)
Interpretation:
The shape of the following ion should be predicted:
Concept Introduction:
The shape of molecule is determined by electron density around central atom as it is suggested by VSEPR theory.
According to VSEPR theory we can determine the shape of a molecule by following the given steps.
- First identify the number of bonded atoms to the central atom and count the number of lone pair of electrons on central atom. Add these.
- The sum obtained above gives us idea about the electronic geometry in a molecule. For example, if it is two then the electron geometry will be linear, if it is three the geometry will be trigonal planar, four the geometry will be tetrahedral, five the geometry will be trigonal bipyramidal, six the geometry will be octahedral.
- Now for molecular geometry we have to consider the number of lone pair of electrons.
- The molecular geometry depends upon the repulsion order between electron pairs which is

Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. CH.
