(a)

Interpretation:

The Lewis structure of molecules or ions, spatial orientation of electron pairs and the simple geometric structure indicating the approximate bond angles of that molecules or ions should be determined.

Concept Introduction:

Lewis structure represents the valence electron arrangement around the atoms of the molecule. Lewis structure can be drawn for ionic or covalent bonds.

When predicting the geometric structure, VSPER theory is used. The three-dimensional structure of atoms in.
